Electrically operating apparatus for circuit breaker

An apparatus for electrically operating a circuit breaker, in which a control panel on a housing of the circuit breaker is provided therein a change-over lever for selectively changing between an electrical operation mode and a manual operation mode, and in which the circuit breaker is operated between the open and closed positions by a drive force from a drive motor during the electrical operation mode and the circuit breaker is operated between the open and closed positions by a drive force from a manual operation handle during the manual operation mode;

• the arrangement being such that said change-over lever moves between an electrical operation mode position corresponding to said electrical operation mode and a manual operation mode position corresponding to said manual operation mode, and that
• said change-over lever has provided therewith a blocking portion which, while allowing the operation of said manual operation handle when said change-over lever is in said manual operation mode position, engages said manual operation handle to prevent the operation of said manual operation handle when said change-over lever is at said electrical operation mode position.
