Challenger CH1020 277V & CH3020 480V etc Breaker TCCs

[W6SJK]

Does anyone have a stash of old printed (or PDF) TCCs that might include Challenger single and three pole 480V breakers? SKM doesn't have them in their development library. Thanks. Eaton hasn't responded to my email.

CH breakers are/were Cutler Hammer, not Challenger. Challenger breakers are just C. Both are available from Eaton, you just have to be clear on which you are looking for.

But neither of those product lines were rated for 480/277. So you have some more digging to do on exactly what you have and need…

Thanks but I beg to differ In any case Eaton finally responded suggesting that I substitute a GHB. Cheers
