摘要
Provided is a multi-pole molded case circuit breaker (MCCB) with an insulation barrier for a rotary pin, in which an insulation barrier is provided in a rotary pin for inter-phase power transmission to prevent dielectric breakdown. The multi-pole MCCB includes a shaft assembly having a movable contactor and having a plurality of rotary pin holes formed in a penetrating manner, a base assembly to which the shaft assembly is rotatably accommodated to be coupled, a switching mechanism coupled to an upper portion of the base assembly and rotating the shaft assembly, a plurality of rotary pins coupled to the plurality of rotary pin holes in a penetrating manner, and an insulation barrier formed of an insulating material and covering the plurality of rotary pins.
