High-level system availability Increasing demand for high quality and efficiency in production is leading to the construction of increasingly complex systems. At the same time, the requirements for safety and availability are tightening because the failure of one machine or major system parts can result in significant costs. Having a well-planned safety concept for individual circuits and end devices throughout the entire system is a significant contribution toward operational safety. This also includes selecting a sufficiently powerful power supply and suitable protective devices. Electronic circuit breakers High functionality, low space requirement and flexible use. With intelligent analysis and signaling of interference, electronic circuit breakers are a perfect way to monitor the system states. They protect system components and switched-mode power supply units against failure.

Many loads are supplied by the same power supply in this type of arrangement. This creates dependencies that are important and critical to system availability. Unscheduled machine downtime must be avoided at all costs. Therefore, it is very important to ensure that if there is a fault, any loads and circuits not involved remain unaffected by the fault. The supply voltage must likewise be maintained in the event of a fault. This is the only way to ensure smooth operation. Using device circuit breakers minimizes potential damage and downtimes by separately protecting individual devices or device groups with device circuit breakers. In this way, end devices are optimally protected against damage or destruction. System parts that are not in the affected circuit continue to operate without interruption to the extent that the overall process allows it. PE N L Potential errors Overload currents Overload currents occur when end devices unexpectedly require a higher current than the intended rated current. Such situations will arise, for example, when a drive is blocked. Temporary starting currents from machines are also considered to be overload currents. Although in principle their occurrence can be calculated, it can vary depending upon the machine load when starting. Take these conditions into account when selecting suitable fuses or circuit breakers for such circuits. Safe shutdown should occur within a range of a few seconds up to a few minutes. Short-circuit currents Short circuits can occur between damaged conductors that are carrying operating voltage. Typical protective devices for shutting down short-circuit currents include fuses and miniature circuit breakers with various tripping mechanisms. Short-circuit currents should be reliably shut down in the milliseconds range. A ms A s 4 Phoenix Contact

Various technologies that provide different forms of protection Phoenix Contact provides thermal, thermal-magnetic and electronic circuit breakers. The differences are in the tripping technology and the shutdown behavior. Characteristic curves are used to clearly illustrate the shutdown characteristics of the various device circuit breakers. Thermal circuit breakers protect via a bimetallic strip that leads to tripping when heated. However, this takes between 300 ms and several minutes. In the event of overloads, this period of time is more than sufficient. The magnetic part of the thermal-magnetic circuit breaker provides protection in the event of a short circuit. If the current suddenly increases, shutdown occurs within a few milliseconds. Electronic circuit breakers reliably protect against both overloads and short-circuit currents, and also offer many advantages. Current and voltage are measured and monitored permanently. Errors are detected far more precisely and quickly. Currents are assessed and shut down sooner or later, depending on their intensity. An electronic circuit breaker will trip at a significantly lower current than an electromechanical circuit breaker. This allows the power supply output to be utilized far more efficiently. Lower reserves can therefore be dimensioned. Device circuit breakers are selected based on the nominal voltage, nominal current, and, if required, the starting current of an end device. The expected error situation - short circuit or overload - then determines the appropriate shutdown behavior.

s r e k a e r b t i u c r i c c i n o r t c e E l Electronic circuit breakers: Intelligent, individual, and intuitive The advantages of electronic circuit breakers • Classification: The currents are evaluated and classified. • Protect and switch: Depending on the class of the analyzed current, the load is started or shut down. The rest of the system thus remains in operation and unaffected. • Signaling: The operating states of all circuits are transmitted continuously to the system operator. If an event occurs, it is detected immediately and reported. Intelligent software is the core of an electronic circuit breaker. The software differentiates between operating currents and harmful currents and rapidly transmits commands to the electronic system. This is because it has to ensure that faults are detected and shut down as quickly as possible while not shutting off an inrush current or normal operating current. The switching operation is performed via the power transistor. Steps to error detection: • Measurement: To monitor the ongoing situation, all electrical variables are measured continuously. • Analysis: The measured values are analyzed in order to determine a course of action. Overcurrents under control Electronic circuit breakers are in some cases equipped with active current limitation. This function limits short circuit and overload currents. It protects the power supply against currents that are too high and prevents the output voltage from dropping at the switched-mode power supply unit. Current limitation The extent of current limitation is described by a factor, normally between 1.25 and 2.0. This value is not exceeded, even in the event of an error. For the power supply, even a hard short circuit therefore has the same effect as a slight overload, the current is significantly lower than without current limitation and the supply voltage to the system remains unaffected. Without current limitation With a circuit breaker without current limitation, the supply voltage can drop out in the event of an error, which means that all the connected devices would fail as well. In other words, in the event of an error, the installed electronics and the integrated firmware must react quickly and intelligently. Although a short circuit must be detected and shut down quickly, it must still be possible to reliably start a capacitive load. STOP 10 Phoenix Contact U I

Setting the device circuit breaker correctly This adjustability also provides you with the option of covering several applications with one device. This not only saves you inventory costs, it also makes selecting the correct circuit breaker much easier. Circuit breakers with fixed values For many, circuit breakers provide a high degree of safety if the current value is not adjustable. In this case, nothing can be adjusted in the system, and all of the settings carried out by the installer remain unchanged. The current values must, however, be determined during configuration. If a value is unsuitable, the entire circuit breaker or protective plug must be replaced. To be able to determine the correct nominal current value for a device circuit breaker, you should know the load(s). However, the actual current often deviates from the manufacturer's information. In a load group, these errors accumulate, which means that the total current deviates even more from the calculated value. Here, adjustable device circuit breakers offer a considerable advantage and remain flexible. Firstly, the set value should not be much higher than the flowing current value. The required starting current of a load can, however, influence the necessary set value. In this case, set the lowest value at which smooth operation can be assured. Adjustable circuit breakers The intelligent software in electronic circuit breakers allows the nominal current to be set individually. This means you can maintain a high level of flexibility throughout. It is not always possible to determine the correct current value right at the start of a project. Adjustability is therefore a useful function, because the final current value can be determined during commissioning. You can provide optimal protection for every load, tailored precisely to the application. Influence of cable lengths Line resistance can limit the flowing current, which means that in the event of a short- circuit, the required tripping current does not flow and shutdown occurs too late. lower tripping current, so only the voltage drop across the line needs to be considered, because if the voltage at the load is too low, the load supply is disrupted. The following applies to electronic circuit breakers: If the load functions in rated operation, the circuit breaker will also trip reliably in the event of a fault.

s r e k a e r b t i u c r i c c i n o r t c e E l Circuit breaker system Supply and communicate centrally The system design starts with the power module. Central feed-in and communication are managed here. All additional modules are supplied directly via the rear-side current rail. With automatic module addressing in the system, no further effort is needed. All system information is collected via the power module and forwarded to the provided interface for evaluation. This ensures that you have transparency across the entire 24 V supply network. Communication The power module is the nerve center of the system. All data and signals are collected here and issued via the status output. The output I >80% issues a signal if the load on a channel reaches at least 80% capacity. You can respond before a failure occurs. You can switch the channels that have been disconnected back on remotely via the reset input. All data can be queried via the integrated PROFINET interface. Configure the channels and keep an eye on the current flowing. You can read off past events from the error log. This reduces troubleshooting times considerably and you have a complete overview of the entire supply. Central feed-in The rear-side current rails of the CAPAROC system are used to supply all modules reliably. By connecting the supply line for positive and negative to the power module, the current rails are also supplied directly. This both reduces the amount of installation work and also eliminates installation errors between the feed-in and the fused connections of each protective module. The current rails connect the power module to every single module in the system. With potential distributors that can be integrated into the system, the return conductor from every fused circuit can be optimally connected in the system. The color-coded push buttons also integrated here make it easy to see what function the respective connections have. This helps to prevent wiring errors. Additional terminal blocks are not necessary. 14 Phoenix Contact

Potentials of the same type can be connected quickly and safely. Push-in connection technology enables you to wire the devices tool-free. This saves time and costs during installation. Active current limitation Active current limitation restricts short circuit and overload currents to a value of 1.25 times the nominal current. This protects the power supply against excessively high currents and prevents output voltage dips at the switched-mode power supply unit. In addition, longer cable paths between the power supply and load are possible without negatively impacting shutdown behavior. s r e k a e r b t i u c r i c c i n o r t c e E l Phoenix Contact 25

CBM device circuit breakers with nominal current assistants The nominal current assistant makes configuration of the CBM exceptionally easy. It enables load currents to be adjusted optimally. Simply turn the potentiometers, until the optimal current has been found. The LED indicates when the ideal setting has been found. Configuring system protection could not be easier. Active current limitation restricts short circuit and overload currents to a value that is 1.5 to 2 times the nominal current. This protects the power supply against excessively high currents and prevents output voltage dips at the switched-mode power supply unit. In addition, longer cable paths between the power supply and load are possible without negatively impacting shutdown behavior. Analysis and signaling The currents flowing are constantly monitored. The CBM not only features a potential-free signal contact to indicate capacity utilization, it also has an 80% output. You are alerted as soon as at least one channel is being heavily utilized. The channel that has been switched off can be easily switched back on remotely via the Reset RST signal input. Differentiate between undervoltages and overvoltages in your system to increase your system availability. The channels are shut down in the event of an error in the operating voltage and the system is switched to a defined state. The error is signaled directly via the remote indication contact. An LED also provides a message directly on the device. 8 channels in a narrow installation space Save space in the control cabinet with the 8-channel CBM E8 device circuit breaker.

Thermal-magnetic device circuit breakers Using thermal-magnetic device circuit breakers Thermal-magnetic device circuit breakers are used among other things in information and communication technology as well as process control. With a variety of versions with different tripping characteristics, the circuit breakers are ideally suited for protecting programmable logic controllers, valves, motors, and frequency converters. The reactivation and immediate remote signaling of the operating state ensure high availability. The different characteristic curves for this protection technology can even start critical loads while at the same time providing secure protection in nominal operation. Tripping characteristics SFB characteristic curve Circuit breakers with the SFB tripping characteristic offer maximum overcurrent protection, even in large systems with long cable paths. SFB stands for “selective fuse breaking,” i.e., selective shutdown. Protective devices with this characteristic curve prevent unnecessarily early switch-off in the event of brief current increases and starting currents during operation, for example. They simultaneously prevent unnecessarily long, persistent overload currents, which may lead to the dangerous generation of heat in operating equipment. M1 characteristic curve Circuit breakers with the M1 characteristic curve trip later than those with SFB or F1 characteristic curves. They withstand starting currents for somewhat longer periods but consciously respond less swiftly to fault situations. In comparison to the direct current characteristic curve, the alternating current characteristic curve is dragged forward on the axis of the nominal current multiple. Even at a lower multiple of the nominal current, alternating currents cause the circuit breaker to trip. F1 characteristic curve Circuit breakers with the F1 characteristic curve trip quickly. They react very quickly to overload situations. However, this can lead to unnecessary shutdowns during operation. This means they offer optimal protection for sensitive loads with very low starting current and thus provide protection over great distances. End devices, which can be damaged by temporary overloads and slightly increased operating current, are also protected by these circuit breakers. ] s [ e m i t g n h c t i i w S 10000 1000 100 10 1 0,1 0,01 0,001 0,5...6 A 8...16 A 1 2 4 6 10 20 40 100 2 4 6 10 20 40 100 Multiples of IN ] s [ e m i t g n h c t i i w S 10000 1000 100 10 1 0,1 0,01 0,001 0,5...6 A 8...16 A 1 2 4 6 10 20 40 100 2 4 6 10 20 40 100 Multiples of IN ] s [ e m i t g n h c t i i w S 10000 1000 100 10 1 0,1 0,01 0,001 0,5...6 A 8...16 A 1 2 4 6 10 20 40 100 2 4 6 10 20 40 100 Multiples of IN SFB characteristic curve M1 characteristic curve F1 characteristic curve AC tripping range Phoenix Contact 37 s r e k a e r b t i u c r i c e c i v e d c i t e n g a m - l a m r e h T

Customizable Pre-wire systems and control cabinets with base elements. Simply install the appropriate protective plug to suit your individual requirements at a later date. If the demands placed on a load change in the meantime, you can simply replace the protective plug. The secure latching ensures that the plug remains firmly in place, even in harsh environments. Large selection of current values A large selection of protective plugs is available in the CB TM range. The nominal currents range from 0.5 to 16 A. Select the right protective plug for your area of application. With the fixed, unchangeable nominal currents of the plugs, you can increase the security of your system. This prevents unintentional changes to the channel currents. Device circuit breakers with SFB characteristic curve Thermal-magnetic device circuit breakers with SFB tripping characteristic provide maximum overcurrent protection – even in large systems with long cable paths. Protective devices with this characteristic curve prevent unnecessary prior shutdown in the event of brief current increases during operation. They simultaneously prevent lengthy overload currents, which may lead to the hazardous generation of heat in operating equipment. This tripping characteristic was specifically developed for use with power supplies that operate on the basis of SFB Technology. Quick and easy installation The device circuit breakers can be easily combined using the unique bridging system from our standard range. Potentials of the same type can be connected quickly and safely. Push-in connection technology enables you to wire the devices tool-free. This saves time and costs during installation. Combining these two devices ensures particularly reliable tripping in the event of a fault, even in the case of long cable runs between the power supply and end device. The SFB characteristic curve is based on characteristic C, but its tolerance is significantly narrower. The circuit breaker therefore reaches its tripping current faster and is tripped sooner. This limits the short- circuit current and reduces the load on cables and connected devices. 1- and 2-pos. plugs Ideal protection for your application. Plugs with various numbers of positions are available for this. Choose single-position plugs for the protection of grounded systems. Use our two-position plug to provide protection across all poles, as is required in insulated systems, for example. This way, you can ensure optimal protection for your system. s r e k a e r b t i u c r i c e c i v e d c i t e n g a m - l a m r e h T Phoenix Contact 39

Thermal device circuit breakers Thermal circuit breakers provide optimal protection against overload for your loads in power distribution systems. When the circuit breaker trips, the integrated switch function enables immediate reactivation. Unlike a fuse, the circuit breaker does not need to be replaced. The higher the overload, the faster the thermal device circuit breaker trips. Thermal device circuit breakers for the DC voltage range The protective plugs can be reset and are suitable for applications up to 40 A DC. More information starting on page 48 Thermal device circuit breakers for the DC and AC voltage range The protective plugs can be switched on and off and are used in applications up to 20 A AC.

Thermal device circuit breakers Field of application Thermal device circuit breakers provide optimal protection against overload for inductive and resistive loads in power distribution systems, control cabinet engineering, and systems manufacturing. They are resistant to high starting currents like those that occur when starting a motor or switching on a transformer. They are also used for protecting circuits in battery and onboard systems. Compared to other protection technologies, however, thermal circuit breakers do not offer rapid protection from short circuits. Tripping characteristics The tripping time of thermal device circuit breakers depends on the overload current that is flowing and the ambient temperature. The characteristic curves show that the tripping time is reached faster as the overload increases. With smaller overload currents, it therefore takes longer for the connected load to be disconnected from the power supply (Fig. 1). For circuit breakers with different nominal currents but the same tripping characteristics, tripping behavior can also be visualized as characteristic curve fields (Fig. 2). Of course, thermal device circuit breakers respond to the effects of heat. The ambient temperature can also affect the tripping time. The circuit breaker trips more easily at a high ambient temperature and more slowly at a low ambient temperature. This behavior is indicated by additional characteristic curves with corresponding information. Function The tripping element of thermal device circuit breakers is bimetallic. It may also be a combination of bimetal and an electrical heating element. The bimetal consists of steel and zinc, which is deformed by heat. When a predefined heat level is reached as a result of an excessively high current in the heating element, the thermal bimetal trips the shutdown mechanism. This thermal tripping element makes the thermal protection more susceptible to higher ambient temperatures. Thermal device circuit breakers represent a simple, cost-effective solution for applications which do not necessarily require fast and precise shutdown. s r e k a e r b t i u c r i c e c i v e d l a m r e h T ] s [ e m i t i g n h c t i i w S ] s [ e m i t g n h c t i i w S 0,25 - 4 A 6 - 20 A + 40°C 10000 1000 100 10 1 + 85°C Typical tripping characteristics for thermal circuit breakers: t Switch time (in seconds) xl Multiple of the nominal current/tripping factor 1 Current ranges of the characteristic field 2 Tripping characteristics of the lower temperature range (blue) 3 Tripping characteristics group 1 4 Tripping characteristics group 2 5 Tripping characteristics of the upper temperature range (red) ] s [ e m i t g n h c t i i w S ] s [ e m i t g n h c t i i w S 0,1 1 4 10 103 102 10 1 4 2 Multiples of IN 10 20 40 Multiples of I TCP/DC32V 5 A -40°C +23°C 4 10 103 102 10 1 TCP/DC32V TCP/DC32V 7,5 A - 30 A 7,5 A - 30 A -40°C -40°C +23°C +85°C 0,1 0,4 1 2 4 10 20 +85°C 0,1 0,4 1 2 Multiples of IN 4 10 20 Multiples of IN Two key characteristic curves of thermal circuit breakers Phoenix Contact 47
