— Safety and protection
Padlocks and key locks Padlocks or key locks prevent the circuit-breaker from being closed and/or opened. They can be fitted: • directly on the front of the circuit-breaker; • on the rotary handle operating mechanism; • on the front for lever operating mechanism; • on the motor; • to the fixed part of withdrawable version, to prevent a moving part from being inserted; • on the front of the thermal-magnetic trip unit, to prevent the adjuster of the thermal part from being tampered with; • on the shutters of the fixed part. In the closed position, the locks do not prevent the mechanism from tripping due to the trip unit or a ser- vice release. Padlocks and keylock for circuit-breaker Type of lock Type of lock
