What are the rating plug part numbers for the CK800 Circuit Breaker?
Product Line:
Circuit Breakers

Environment:
CK800 Circuit breaker

Resolution:
CK800 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 CK800 class of breakers includes many different actual catalog numbers. For the Rating Plug part numbers for the CK800, following are the part numbers:
400A - part number 35311
500A  - part number 35312
600A - part number 35313
700A - part number 35314
800A - part number 35315

Regarding availability, note that these Rating Plugs, and the CK800 Circuit Breakers themselves, are all obsolete and no longer available. If necessary to replace an existing CK800, 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 CK800. 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.
