User-friendly, easy, and intuitive – the ideal protection for your system.
The CBM and CBMC multi-channel electronic circuit breakers provide greater functionality while taking up less space. Due to Push-in connection technology, they are particularly suitable for use in machine building and control technology.
Four to eight channels can be safely protected against overload and short-circuit currents with the CBM multi-channel device circuit breakers. Thanks to the integrated nominal current assistant, setting the right nominal current for your consumers is easy. The selected settings are locked electronically. This prevents the risk of unwanted incorrect settings.
The integrated early warning system ensures fewer failures. When the set nominal current of a channel reaches 80%, a warning is output via the associated LED. Furthermore, the separate signal output can be used for remote signaling.
Active current limitation enables optimum use of the upstream power supply. This enables the use of smaller switched-mode power supply units and prevents unwanted voltage dips.
The nominal current assistant makes configuration of the CBM exceptionally easy. It enables optimal adjustment of the load currents. Simply turn the potentiometers until the optimum current has been found. The LED displays the ideal setting. It could not be easier to configure the system protection.
Active current limitation restricts short-circuit and overload currents to a value that is 1.5 to 2 times that of the nominal current. This protects the power supply against excessively high currents and prevents the output voltage from dropping at the switched-mode power supply unit. In addition, longer cable paths between the power supply and consumer are possible without negatively impacting the shutdown behavior.
The CBM can be adjusted in precise nominal current steps. The nominal current ranges from 0.5 to 10 A. You can therefore adjust the channels individually to the nominal currents of the connected end devices. You can make the settings individually for each channel. This means that one device can be used for a wide range of consumers.
The currents flowing are constantly monitored. The CBM not only features a floating 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 then 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 indicates the error directly on the device.
Save space in the control cabinet with the CBM E8 8-channel device circuit breaker. Reliably protect eight channels against overload and short-circuit currents in just one device with an overall width of just 41 mm. Reduce inventory costs and also ensure the highest flexibility in system planning.
The CBMC electronic circuit breaker is tailored precisely to your requirements: it combines a compact design and individual adjustability. The four channels can be adjusted via the LED button easily and with no need for tools.
The integrated early warning system ensures fewer failures with CBMC, too. When the set nominal current of a channel reaches 80%, a warning is output via the associated LED.
CBMC also provides the right solution for NEC Class 2 circuits. The adjustable devices for one to four amps provide ideal protection for cables and sensors.
This means that you can easily and flexibly adjust currents, save space, and reliably protect all applications with just a single device.
Save space in the control cabinet with the CBMC, or convert existing systems with a minimum of effort. Thanks to the combination of compact overall width and individual adjustability, selecting the correct product is easy, and at the same time you save inventory costs, as only one device is required.
One-button operation makes adjusting individual circuits easy. This allows you to adapt the channels of the device circuit breaker individually to meet your needs, and without any tools.
Order your device circuit breakers preconfigured starting from a minimum quantity of one unit. You receive the device ready-made for your system. This preconfiguration saves you valuable time during startup. You can choose whether the settings are to remain adjustable or are to be fixed to provide protection against tampering.
The 1 - 4 A version is approved in accordance with NEC Class 2. You can therefore easily configure energy-limited circuits with CBMC. Instead of an NEC Class 2 power supply unit, simply use your powerful standard power supply unit. Benefit from quicker and easier installation and testing of your application.
Get the best protection for your system and order device circuit breakers that are preconfigured according to your requirements. You save programming time and can install and start the product up immediately.
You decide at the time you place your order which presets you would like the device to have. Each individual nominal current is selected individually. You are also free to decide whether you would like to be able to change the preset values later or want them fixed permanently. With fixed values, the current values for each channel are even printed directly on the front. You can therefore easily see the device circuit breaker settings at any time, even once it has been installed.
Order your fully customized device circuit breaker in the quantities you want, starting from a minimum quantity of one unit.
To make reordering as easy as possible, every device has an order code affixed on the side. This enables seamless reordering.
The CBMC portfolio also includes versions with IO-Link interface. IO-Link enables you to fully integrate the device circuit breakers into the process monitoring and control systems. This gives you continuous access to process-related data and keeps you up to date on them from anywhere.
Device circuit breaker versions equipped with status output and reset input give you more diagnostic and control options in your system. This is because this product provides the option of remotely resetting the circuit. It is therefore also possible to install the device circuit breaker in locations that are difficult to access.
Another version electrically interrupts load outputs with the help of built-in relays. In this case, as opposed to other electronic circuit breakers, the protected output is not only switched to high impedance in the event of an error, but is also electrically isolated.
