Compact® NSF and NSJ 150 to 600 A Circuit Breakers
Section
Interlocking with Keys
For circuit breakers equipped with rotary handles or a motor mechanism. Interlocking with keys may be easily implemented by equipping each of the Compact® circuit breakers, either fixed or drawout mounted, with a directly mounted rotary operating handle and a standard keylock, but with only one key for the two keylocks. This solution enables interlocking between two circuit breakers that are geographically distant or that have significantly different characteristics.
Use:
•A keylock adapter (different for each device)
•Two identical keylocks with a single key
