household electrical leakage open circuit protection DZ47 small circuit breaker household air switch.

Brief introduction

DZ47 series small circuit breaker is a kind of limited current high breaking small circuit breaker with double protection of overload and short circuit. It is mainly used for overload and short circuit protection of electrical lines and equipment in modern buildings, and is also suitable for infrequent operation and isolation of lines.

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.
