Claims

[Scope of utility model registration request]

(1) A plurality of coaxially arranged fixed contacts that are electrically insulated and separated from each other, which are inserted and penetrated corresponding to the fixed contacts, are electrically insulated and separated from each other, and are integrally coupled coaxially. A current-carrying arc contact is arranged in series on the same axis, and the sliding, insertion, and removal of the movable contact causes a connection between the movable contact and the fixed contact. In a breaker that conducts or interrupts current by forming a closed circuit or an open circuit in series, the sliding direction of the movable contact to open the circuit with respect to the fixed contact is coaxial with the fixed contact. and an intermediate fixed contact located at such a position that the movable contact is inserted and energized only when the movable contact is in a closed circuit state, and electrically connected to the intermediate terminal plate. A circuit breaker characterized by:

(2) The intermediate fixed contact electrically connected to the intermediate terminal plate is fixed to the intermediate terminal plate and has a communicating hole formed therethrough and a counterbore opening formed in the center thereof. The circuit breaker according to claim 1, which is an intermediate fixed contact provided with an intermediate terminal block and electrically connected by attaching an intermediate fixed contact to the dust hole opening of the intermediate terminal block. .
