Circuit breaker body, circuit breaker body side disconnection section that disconnects the wiring of the operation control circuit that is provided in the circuit breaker body and controls the circuit breaker body to be turned on and off, and this circuit breaker body side disconnection section is provided detachably. Cover the cubicle side disconnection part connected to the wiring of the operation control circuit, the operation part operated to insert / remove the cubicle side disconnection part, the operation part so that it can be contacted only from the bottom side, and the breaker body is disconnected A cover that can contact the operation unit without being interrupted by the plate-like rail only when it is positioned.

以上のようにこの発明によれば、操作制御回路のキュービクル側断路部を抜き差しするように操作する操作部を設けるとともに、操作部を下面側からのみ接触可能なように覆い、遮断器本体が断路位置に位置しているときのみ板状のレールに遮られることなく操作部に接触可能とするカバーを設けたので、遮断器本体が接続位置に位置しているときには、操作部はその下面側以外はカバーに覆われるとともに、操作部の下面側は板状のレールに遮られるので、操作部への接触は不可能となる。このため、キュービクル側断路部を操作する操作部が操作不可能となり、キュービクル側断路部を遮断器本体側断路部から引き抜くことができず、操作制御回路は断路不能となる。又、遮断器本体が断路位置に位置しているときには、操作部の下面側はレールに遮られないので接触可能となり、操作部を操作してキュービクル側断路部を遮断器本体側断路部から引き抜くことができ、断路可能となる。従って、移動形遮断器の必要条件を満足させることができる。又、カバーは操作部を下面側のみ接触可能なように覆うだけであるから、これらの構造は簡単となり、製造が容易で安価となる。   As described above, according to the present invention, the operation unit that operates so as to insert and remove the cubicle-side disconnection part of the operation control circuit is provided, and the operation part is covered so that it can be contacted only from the lower surface side, and Since the cover is provided so that it can contact the operation part without being blocked by the plate-shaped rail only when it is in the position, when the breaker body is in the connection position, the operation part is other than its lower surface side Is covered with a cover, and the lower surface side of the operation portion is blocked by a plate-like rail, so that it is impossible to contact the operation portion. For this reason, the operation part which operates the cubicle side disconnection part becomes inoperable, the cubicle side disconnection part cannot be pulled out from the circuit breaker body side disconnection part, and the operation control circuit cannot be disconnected. In addition, when the breaker body is located at the disconnect position, the lower surface side of the operation unit is not blocked by the rail so that it can be contacted. Can be disconnected. Therefore, the requirements for the mobile circuit breaker can be satisfied. Further, since the cover only covers the operation part so that only the lower surface side can be contacted, these structures are simple, and the manufacture is easy and inexpensive.

Therefore, in the connection position (operating position) where the breaker body 2 is located on the back side on the rail 3, the operation unit 7 is blocked by the rail 3 on the lower surface side and cannot move the operation unit 7 with a finger. The disconnection part 5 cannot be pulled out from the disconnection part 4 and cannot be easily disconnected. When the circuit breaker body 2 is in the connection position, the circuit breaker body 2 can be turned on only when the operation control circuit is connected. Furthermore, when the circuit breaker body 2 is in the connected position and the circuit breaker body 2 is in the on state, the circuit breaker body 2 is automatically disconnected when an accident occurs in the main circuit. Each requirement of the type circuit breaker can be satisfied.

又、カバー8は操作部7を下面側のみ接触可能なように覆うだけであるから、これらの構造は簡単となり、製造が容易で安価となる。さらに、カバー8は直接的には操作部7を覆い、間接的にはキュービクル側断路部5を覆うので、配線6を保護し、信頼性を向上することができる。   Further, since the cover 8 only covers the operation unit 7 so that only the lower surface side can be contacted, these structures are simplified, and the manufacture is easy and inexpensive. Furthermore, since the cover 8 directly covers the operation unit 7 and indirectly covers the cubicle-side disconnection unit 5, the wiring 6 can be protected and reliability can be improved.
