PROBLEM TO BE SOLVED: To prevent a circuit breaker from being drawn out of an operating position while it is turned on. SOLUTION: A fixed frame 2 has an operating member 15 with a guide face 15a slanted in a drawing-out direction of a movable frame 1, on which a circuit breaker 6 is fixed. An interlocking lever 16, which receives tension of an interlocking spring 25 and is slid in a contacted state with the guide face 15a through a contact pin 21, and a trip lever 17 interlocked with the interlocking lever 16 through an interlocking pin 23 are mounted pivotally on the movable frame 1. The movable frame 1 is supported by the fixed frame 2 in a horizontally slid state, and a pushing spring 27 is provided opposite to a trip button 9 of the circuit breaker 6. When the breaker 6 is drawn out, the interlocking lever 16 is turned along an operating member 15, and the interlocked trip lever 17 pushes the trip button 9 through the pushing screw 27 to open the circuit breaker 6. |
