Claims

[Scope of utility model registration request]

In a closed switchboard in which a wiring breaker and an electromagnetic contactor connected in series with the circuit breaker are provided in drawer-type units and housed in multiple stages, a unit door provided for each of the above units and a separate door for the electromagnetic contactor are installed. a lock lever provided in the unit so as to be interlocked with a movable part that protrudes and retracts depending on whether or not the electromagnetic contactor is energized; and a lock lever provided on the unit door side in which the electromagnetic contactor is in an energized state. a closed switchboard having locking plates arranged to engage with each other;
