The Lug part numbers are needed for a CK circuit breaker, as well as information on availability of the lugs.
Compact CK Circuit Breakers, and the Lugs, are obsolete and no longer available. These types of breakers were sold under the name of Merlin Gerin, which was acquired by Schneider Electric in 1992. Details, ratings, and dimensions of the CK breakers can be found in the attached three documents.
If necessary to replace an existing CK breaker, our currently produced circuit breakers can perform the same function. Note, however, that the new breaker dimensions, lugs, and other accessories are different than the CK breakers. Be sure to check this for your particular application. Details of our current breakers can be found in our online Digest at this link. To speak with someone, call us at 888-778-2733, and ask for Technical Support for Circuit Breakers.
