Technical FAQs 4

What are thermal magnetic circuit breakers?

Thermal magnetic circuit breakers are devices that provide protection against overcurrent in circuits. Circuit breakers use an automatically operated electrical switch to disrupt the flow of current when an overload or short circuit is detected. Thermal magnetic circuit breakers do this using an electromagnet and bimetallic strips.

What are the different types of thermal breakers?

Thermal breakers protect circuits from excess current in a similar way to a fuse, however, they often feature a switch allowing them to be reset if tripped. Common types of thermal breakers include thermal magnetic circuit breakers and thermal automotive circuit breakers.

What are thermal automotive circuit breakers used for?

Thermal automotive circuit breakers are used to protect electrical networks in most types of vehicles, including cars, vans, buses, and boats. Shop our range of Thermal Magnetic Circuit Breakers supplies & accessories. Free Next Day Delivery.

What is the trip time of a thermal circuit breaker?

The trip time of thermal circuit breakers depends on the height and of the duration of the overload current and the ambient temperature. With higher current ratings, the bimetal or hot wire is heated up until the defined trip time is reached and the device ensures genuine physical isolation of the contacts. It's only a circuit breaker.
