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
