ECN Forum Forums General Topics of the Trade General Discussion Area Can someone tell me what Breaker this is?

Square D and Cutler-Hammer were never the same company. There have been many situations when the "brand labeled" componenets between each other, but that is true of most electrical manufacturers.

In this case Square D sold the manufacturing rights to the XO breaker to C-H back in the 70's.
