Device circuit breakers for protection against overcurrent and short circuits are divided into 3 groups: thermal circuit breakers, thermomagnetic circuit breakers, and electronic circuit breakers.
Thermal circuit breakers.
TCP thermal circuit breakers provide protection for inductive loads against overload in current distribution systems in control cabinet and plant engineering.
Thermomagnetic circuit breakers.
In IT and communication technology, process control systems, as well as devices and systems, TMC thermomagnetic circuit breakers provide protection against overload and short circuits.
Electronic circuit breakers.
ECP and ECP-E electronic circuit breakers have been developed to provide clear protection, even in 24 V DC load circuits. They protect all loads that are supplied by a switched-mode power supply unit.
