Abstract
Disclosed herein is a pole component assembly for a circuit breaker. The pole component assembly for a circuit breaker includes an external insulating housing made by injecting resin into a housing mold, applying injection pressure to mold the injected resin, and separating the molded resin from the housing mold, and a circuit breaker portion assembly detachably inserted into the external insulating housing after the external insulating housing is made. According to embodiments of the present disclosure, the external insulating housing is molded without a main circuit breaker component when manufacturing a sealed type pole component, and the main circuit breaker component is assembled into the finished external insulating housing, thereby preventing the main circuit breaker component from being contaminated or damaged.
