Abstract
Disclosed is a keylock device for a circuit breaker. The keylock device for a circuit breaker comprises a closing lever configured to generate a closing operation of a mechanism, a trip lever configured to generate a trip operation of the mechanism, and a locking unit configured to allow a locked state of the locking unit to be maintained when the mechanism is in an 'ON' state, but to allow the locked state of the locking unit to be converted into a released state when the mechanism is in an 'OFF' state. Under these configurations, it is impossible to convert the current state of the keylock device into a locked state unless the mechanism of the circuit breaker is converted into an ‘OFF’ state. This may prevent the occurrence of an accidence due to the operator's unintentional ‘OFF’ state of the mechanism.
