CB operating Mechanism

[ptonsparky]

I need to find the operating mechanism(s) for CH circuit breakers.

C370KD41 thru C370KD44.

Parts of the disconnects mech are misssing & I don't like turning on 600 to 1200 amp cbs with the door open.

PM or send me in a direction if you can.

Pton I can put you in contact with a KNOWLEDGABLE sales rep if you like and also an after market guy.

Brian, I sent pictures to Gordon & he pointed out another problem I had not noticed. Could be another fun project.

Thanks.

I have mechs for every breaker ever made but never heard of C370KD41 thru C370KD44. Whats the rest of the nameplate info?

They are the actual catalog numbers for the mechanisms. Cutler Hammer MCC, 1976. They used Westinghouse breakers.

I took a closer look today. Rained, so I could shut things down. The main breaker mechanism is just not there, the 2nd mech. has been damaged due to an arc flash at some time & part of it needs replaced. The third CB was replaced with a 600A SQD breaker instead of Westinghouse and nothing original will fit that.
