What is the part number of a replacement key for a cylinder lock installed in a Molded Case Circuit Breaker?
Legacy F, K, L and M frame breakers
This covers all FA/FH, KA/KH, LA/LH, MA/MH breakers with cylinder locks
The keys for the cylinder locks have been lost or damaged.
There are no replacement keys available for these cylinder locks. For the FA/FH, KA/KH breakers, cylinder locks are only available as factory installed. In the case of FA/FH, a new breaker would have to be purchased (the KA/KH is obsolete and not available). In the case of the LA/LH and MA/MH, new field installable cylinder lock kits can be purchased. They are LA1CL and MA1CL (this kit is now obsolete and no longer available).
