SCHURTER builds on thermal release technology

Thermal circuit breakers

Traditionally, circuit breakers are based on the thermal principle, utilising a bimetal strip. When an overcurrent causes the temperature to rise beyond a specified limit, the circuit is interrupted. Once the bimetal cools down, the device can be reset and used again. However, in the case of a short circuit, the response time of the bimetal is insufficient, necessitating the use of a fuse in conjunction with the thermal circuit breaker.

Enhanced protection with magnetic module

SCHURTER has now enhanced its two-pole TA35 and TA36 models by introducing an optional magnetic module. This upgrade eliminates the need for an additional fuse when using a thermal-magnetic version. Depending on the application, the magnetic modules are available with either a slow or fast acting response.

Both the TA35 and TA36 are designed for snap-in mounting and offer a finely graduated range of rated currents. The availability of various colours and lighting options provides designers with greater flexibility. The TA35 retains a classic appearance, while the TA36 features a more contemporary design.

Circuit breakers equipped with short circuit protection are particularly suited for applications where comprehensive primary side protection is essential.
