The lock-off attachment is a permanently installed, side mounted accessory for the C60 circuit breakers to allow locking the circuit breaker in the off position. The attachment is available for right or left side application and is made of optically clear materials so text on the side of the circuit breaker can still be read after installation. The lock-off attachment accepts a 1/4 to 3/8 in (6 to 9.5 mm) Dia padlock, which is not supplied.
