Claims

[Scope of utility model registration request]

(1) A drawer frame having a power supply side conductor, a load side conductor, and a ground conductor, each of which is provided to protrude inward, and a primary conductor that is inserted so as to be drawable and connected to the power supply side conductor via a primary side contactor. a breaker body connected to a side conductor and the load side conductor via a secondary side contactor and opening/closing between the secondary side conductor and the secondary side conductor; - a grounding device having a grounding contact attached to a next-side contactor or the second-side conductor after removing the second-side contactor or the second-side conductor and connected to the grounding conductor; The grounding conductor is a pair of neutral poles of a four-pole drawout type circuit breaker, and the pair of neutral poles are connected by a U-shaped conductor.

(2) The grounding device consists of a current-carrying member that short-circuits each phase of the primary conductor or secondary conductor after the secondary contact or secondary contact has been removed, and one end of the current-carrying member. and a grounding contact provided and connected to a grounding conductor. A draw-out type circuit breaker according to claim (1) of the utility model registration.
