Environment:
CK1000 Circuit breaker

Resolution:
CK1000 is a general description for a class of circuit breakers, which are a part of our line of Compact CK Circuit Breakers. These were sold under the name of Merlin Gerin, which was acquired by Schneider Electric in 1992. The CK1000 class of breakers includes many different actual catalog numbers. For the Rating Plug part numbers for the CK1000, following are the part numbers:
500A  - part number 35321
600A - part number 35322
700A - part number 35323
800A - part number 35324
1000A - part number 35325

Regarding availability, note that these Rating Plugs, and the CK1000 Circuit Breakers themselves, are all obsolete and no longer available. If necessary to replace an existing CK1000, a currently-produced circuit breaker can be used that will perform the same function. It is very important to note, however, that the new replacement circuit breaker will be of different size and mounting dimensions compared to the CK1000. The terminals and accessories will also be different. To help clarify dimensions and ratings of the obsolete CK circuit breakers, see the attached two files.

When choosing the replacement circuit breaker, there may be several possibilities from which to choose. Our online Digest includes much of this information (click this link). To speak with someone, call us at 888-778-2733, and ask for Technical Support for Circuit Breakers.
