Super-fast tripping modules in the event of a short circuit

SCHURTER, in addition to their thermal release (bi-metal), the classic TA35 and TA36 are now optionally equipped with an extra magnetic module, which promises reliable protection within milliseconds in the event of very high overcurrent (short circuit).

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

The company is now upgrading its two-pole classic TA35 and TA36 models with an additional, optional magnetic module. From now on, no extra fuse is needed when using a thermal-magnetic type. The magnetic modules are available with a slow or fast-acting characteristic, depending on the application.

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

A circuit breaker with short circuit protection is mainly intended for applications where full protection on the primary side is needed.
