Thermal-magnetic circuit breakers

Circuit breakers are usually designed according to the thermal principle with a bimetal. If a defined temperature is exceeded due to overcurrent, the electric circuit is interrupted. Once the bimetal cooled down, the appliance is ready for use again. However, if a short circuit occurs, the bimetal cannot react fast enough. For this reason, thermal circuit breakers are usually combined with a fuse.

SCHURTER is now upgrading its 2-pole classic TA35 and TA36 models with an additional, optional magnetic module. From now on, no additional fuse is required when using a thermal-magnetic type. Depending on the application, the magnetic modules are available either with a slow or a fast acting characteristic.

Both models are designed for snap-in mounting and with finely graduated rated currents. A variety of colours and lighting options make the designer's choice easier. The SCHURTER TA35 has a more classic style, while its TA36 counterpart comes in a more modern design.

A circuit breaker with a short circuit protection is mainly meant for applications, where a full protection on the primary side is required.
