Abstract

The present invention relates to a circuit breaker for wiring, and more specifically, to a circuit breaker for wiring having an insulating cover. In a circuit breaker for wiring according to an embodiment of the present invention, an external connection device is connected to the load-side terminal portion, and the circuit breaker for wiring includes an insulating cover coupled to the wiring circuit breaker. In the case of a line circuit breaker, the insulating cover includes an insulating wall portion inserted between the case and an external connection device.

Description

technical field [0001] The present invention relates to a circuit breaker for wiring, and more particularly, to a circuit breaker for wiring having an insulating cover. Background technique [0002] Generally, a wiring circuit breaker (MCCB: Molded Case Circuit Breaker) is an electrical device that protects the circuit and the load by automatically cutting off the circuit in the event of an electrical overload state or an electrical short-circuit fault. It can form a circuit connection with the back part; the mechanism part is divided into fixed terminals and movable terminals and mechanically opens and closes the circuit; the trip part guides the trip of the mechanism part by detecting the overcurrent or short-circuit current generated on the circuit Action; Arc extinguishing part is used to extinguish the arc (Arc) generated when the abnormal current is cut off. [0003] Among such circuit breakers for wiring, a circuit breaker for wiring that is used to connect to a main...
