Thermal-magnetic circuit breakers feature a thermal tripping mechanism as well as a magnetic tripping mechanism. This means that the protective devices trip faster in the event of a short circuit compared to thermal fuses. With their various characteristic curves, the device circuit breakers also satisfy the requirements for long cable paths. They therefore provide ideal protection against overload and short-circuit currents.

With an overall width of 8 mm, the new PTCB TM product family creates more space in the control cabinet. It is also ideal for higher currents and can be bridged to the CLIPLINE complete range. Through electrical isolation and easy current monitoring, it provides reliable protection.
The PTCB TM product family offers a highly compact, thermal-magnetic circuit breaker system. The individual circuit breakers have an overall width of just 8 mm and feature integrated signaling. The base elements can be bridged to the CLIPLINE system. The tool-free Push-in connections simplify wiring. Other highlights include current monitoring, remote signaling options, and intuitive handling. This makes PTCB TM ideal for modern control cabinet solutions.
The UT 6-TMC thermal-magnetic device circuit breakers provide reliable protection against overload and short circuit in a one-piece, easy-to-install design. With a clearly defined characteristic curve, the series focuses on proven applications. Ideal for modular systems with high availability and easy handling.
PTCB TM and UT 6-TMC thermal-magnetic circuit breakers
Thermomagnetic device circuit breakers are tripped both thermally and magnetically. The two systems, bimetal and solenoid, operate independently of one another.
In the case of thermal-magnetic circuit breakers, the tripping mechanism is activated within 3 to 5 ms in the event of a short circuit. This is faster than with purely thermal circuit breakers.
Use device circuit breakers with fast characteristic curves, such as F2 curves, to realize longer cable runs in your system. In conjunction with QUINT POWER power supplies from Phoenix Contact, you can achieve maximum protection for your cables and devices. The device circuit breakers can be switched on again at any time.
Our thermomagnetic device circuit breakers are available in a one-piece and a pluggable design. Choose between screw connection and Push-in connection technology.
Circuit breakers are installed in the control cabinets of a wide range of machines
Thermal-magnetic device circuit breakers are primarily used in information and communication technology as well as in process control. Due to the various tripping characteristics and precise nominal current levels, the device circuit breakers can be used in a wide range of applications.
For example, they are ideal for protecting programmable logic controllers, valves, motors, and frequency converters.
