QOU circuit breaker
Mechanical interlock attachment
Used to interlock two circuit breakers mounted side by side so that only one breaker can be on at a time
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
The mechanism will still be able to trip and open the contacts even if the handle is held on
