low voltage circuit breaker DZ47 miniature circuit breaker DZ47 leakage circuit breaker leakage protector.

Working principle of product

A small circuit breaker is the principle that the bimetal bending is directed regularly with the increase of temperature. When the circuit breaker is closed in normal working condition, the internal bimetallic sheet is heated by a certain current, and the thermal expansion coefficient of the two bimetalles is different. It is not enough to release the release mechanism. When the line appears general overload, when the overload current is reached, the bimetallic sheet has a larger bending angle and a lever in the release mechanism, which is enough to push off the release mechanism, and from the small circuit breaker, it plays the role of super load protection. The size of the bimetallic strip is different from that of the small circuit breaker.
