Thermal Overcurrent Circuit Breakers
Thermal circuit breakers (circuit protectors, resettable fuses, circuit breakers for equipment protection) are ideally suited to overload protection of motors, transformers, magnetic valves, on-board electrical systems and low voltage lines.
With simple operations through the heating effect of current, thermal circuit breakers offer one of the most reliable and cost effective forms of protection device available. As a result they are ideally suited to the protection of a broad range of components and systems such as transformer windings, printed circuit boards, low voltage power distribution circuits of road vehicles and battery powered machines.
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.
