Hey Curt,
The letter from UL to Eaton shows the BR as being a replacement for the Challenger type C, for whatever reason the CL is no ton the list. I am not an expert on alternative breakers, I will look up the CL.
Thanks!
CL is not on the list because it is not the UL listed replacement for type "C" or Type "BR" breakers. CL is a classified breaker that is designed to be used in may different panels.
There are some jurisdiction in my area the will not accept classified breakers. The breakers must be the same type that the panel label shows. Its kind of funny that UL states that that the instructions included with equipment must be followed yet when it comes to classified breakers they say we can ignore the panel instructions.
Back to the Type "C" and "BR" breakers. BR is the original type breaker for Bryant panels. When Westinghouse purchased Bryant distribution equipment they kept the BR breaker. Later Westinghouse purchased Challenger which used type "C" breakers. Instead of combining the 2 brands into one Westinghouse kept them separate. They did consolidate the product so it was the same for both brand names. You could buy a Westinghouse loadcenter or a Challenger loadcenter and they were identical except for the name. They did eliminate the original Challenger Type "C" and Type "A" circuit breakers. The replaced the "C" and "A" breakers with the Bryant "BR" design but printed "C" or "A" instead of "BR" on them.
When Cutler Hammer acquired the Westinghouse distribution equipment they consolidated the Westinghouse and Challenger equipment into one line of Cutler Hammer equipment. They started marking all of the circuit breakers with both Type "C" and "BR" so they could be use in all new equipment plus all existing Bryant and Challenger equipment.
Siemens is doing almost the same this as Westinghouse did. When they purchased Crouse Hinds distribution equipment they renamed the line back to Murray which is what is was before it was Crouse Hinds. They eliminated all of the original Murray/Crouse Hinds designs and replaced them with ITE/Siemens designs. The Siemens Type "Q" circuit breakers is the exact same breaker as the Murray Type "MP" except for the label. I wish they would just consolidate the lines and label the breakers with both types.
