Handle Tie

The handle tie accessory converts any two adjacent one-pole QO circuit breakers to one independent

trip multi-pole circuit breaker.

Handle Lock-Off (Clamp)

The handle lock-off accessories fasten the handle in the ON or OFF position. These handle lock-offs

cannot be padlocked.

Handle Padlock Attachment

The handle padlock attachment allows padlocking the circuit breaker handles in either the ON or OFF

position or in the OFF only position. Handle padlock attachments are available in two styles: removable

and fixed.

The removable style is intended to be a temporary device. Once work on the circuit breaker has been

completed, the attachment can be removed from the circuit breaker to resume normal operation.

The fixed style is intended to be a permanent device. Once the work on the circuit has been

completed, the padlock can be removed for the circuit breaker to resume normal operation, but the

attachment stays in place.

Mechanical Interlock Attachment

The mechanical interlock attachment locks the handles of two adjacent circuit breakers to prevent both

circuit breakers from being on at the same time. Both circuit breakers may be switched to the off

position with the mechanical interlock in place.

Mechanical Interlock Attachment with Retaining Kit

The mechanical interlock attachment locks the handles of two adjacent back-fed circuit breakers in

dual power supply applications.
