Abstract
DISCLOSED IS A KEY LOCK DEVICE (240) FOR A CIRCUIT BREAKER CONFIGURING A LOCK MEMBER (290) FOR PREVENTING A CONNECTION LINK (232) FROM BEING MOVED TO BE LINEARLY MOVABLE, THEREBY ENABLING TO ENHANCE THE RELIABILITY IN A LOCKED STATE, AS WELL AS REDUCING AN INSTALLATION SPACE. FURTHER, THE KEY LOCK DEVICE (240) FOR THE CIRCUIT BREAKER IS FIXED ONTO A PANEL (215) FIXED TO THE UPPER PORTION OF A SWITCHING MECHANISM (210), THEREBY ENABLING TO ENHANCE THE RELIABILITY OF THE OPERATION, COMPARING WITH THE RELATED KEY LOCK DEVICE (240) FIXED TO A COVER COVERING THE FRONT SIDE OF THE CIRCUIT BREAKER. FURTHER, THE KEY LOCK DEVICE (240) FOR THE CIRCUIT BREAKER IS PROVIDED WITH A PLURALITY OF KEY BODIES (260), AND THE KEY BODIES ARE OPERATED AT THE SAME TIME SO AS TO RELEASE THE CIRCUIT BREAKER FROM THE LOCKED STATE, THEREBY ENABLING TO ENHANCE THE RELIABILITY WITH RESPECT TO THE LOCKED STATE.
