PURPOSE:To eliminate the need for exclusive machining for mounting a clamp, and to mount the clamp easily at low cost by holding the clamp between a disconnector and a mounting plate. CONSTITUTION:A sliding plate 5A is installed stidably onto a mounting frame 6 by a pin 9. A clamp 7A is fixed onto a mounting plate 10 by a nut. A breaker mounting screw 8a fixes a circuit breaker 1 to a disconnector 2 through the clamp 7A. When the circuit breaker 1 is turned ON, the circuit breaker 1 is covered with the sliding plate 5A, and brought to the state in which it cannot be detached. When the circuit breaker 1 is turned OFF, the sliding plate 5A is interlocked with a handle 1a, engagement with the clamp 7A is released, and the circuit breaker 1 can be dismantled from the disconnector 2. Accordingly, exclusive machining for fixing the clamp 7A is unnecessitated. |
