Thermal Overcurrent Circuit Breakers

Typical Applications

E-T-A thermal overcurrent circuit breakers are ideally suited to protect against overcurrent and short circuit of a broad range of equipment and systems - from motors and transformer windings, through printed circuit boards, to the low voltage power distribution circuits of road vehicles, boats and battery powered machines.

Technology

The trip time of thermal circuit breakers depends on the overload current. The heating effect of current heats up the bimetal or hot wire until the tripping point is reached and the breaker provides genuine physical contact isolation.
