摘要： A circuit breaker includes an elongated movable contact having a contact at one end thereof for flowing a current therethrough and the other end rotatably supported with a holder, and a protection cover made of an insulating material for covering and protecting a movable contact from short circuit and discharge. The protection cover is made of only the insulating material, covers the movable contact, and has elasticity to tightly hold the movable contact.

摘要： A molded case houses switching parts and includes a case main body and a cover placed on an upper portion of the case main body. The case main body includes a bottom portion case that forms a bottom portion of a circuit breaker and an intermediate case, placed on an upper portion of the bottom portion case, having a dividing wall that blocks off a space between the intermediate case and the bottom portion case. A power source side terminal block and second movable contact are fitted inside the bottom portion case, and a first movable contact, the load side terminal block, the contact portion, and the arc extinguishing chamber are fitted inside the intermediate case.
