Regarding availability, note that these Rating Plugs, and the CK400 Circuit Breakers themselves, are all obsolete and no longer available. If necessary to replace an existing CK400, 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 CK400. 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.
