Title:

OPERATION DEVICE OF CIRCUIT BREAKER FOR WIRING

Document Type and Number:

Japanese Patent JPH09306325

Kind Code:

A

Abstract:

To reliably switch a manual mode and a motor-driven mode to/from each other in an operation device to operate an operation handle of a circuit breaker for wiring by manual operation and motor-driven operation.

When a shaft 15 rotates, torque of the shaft 15 is transmitted to an operation handle 11a of a circuit breaker 11 through a slider 20 from a cam 18, and the operation handle 11a can rotate between an ON position and an OFF position. In this constitution, when an operation hole 13b is blocked up by rotatably operating an auxiliary cover 24, a condition of a microswitch 26 is switched, and since a control circuit for motor-driven operation is closed, motor-driven operation of the shaft 15 becomes possible. When the operation hole 13b is opened by rotatably operating the auxiliary cover 24, a condition of the microswitch 26 is switched, and since the control circuit is opened, manal manual operation of the shaft becomes possible through the operation hole 13b.
