6 pole circuit breaker

Just a guess, perhaps the individual poles of the bus are not rated to deliver the required current so this breaker is designed to connect to two poles of each bus. Again, just a guess I've never seen one of those.

Those don't appear to be factory labels.

Thx for the responses. I'm not finding that breaker through any part # searches so it doesn't seem like a manufactured product. And I am still a bit baffled how they wired onto it. You'd have to combine 6 wires into 3. I wish I could pull off the panel cover. 240.8 would prohibit making your own parallel breaker.

I dont think it has 6 terminations - The breaker combines them into 3. Its because they cant pull that much current off a single bus finger. I have seen two poles that take up for spaces, but horizontally no 4 verticallly on one side, never seen a three pole, let alone one that does it in a vertical config. I am dying to know how much that cost. Did you google the part number shown in the pic?
 
Yeah a common 1, 2 or 3 pole breaker for that panel is hard to find around here, I'd hate to try to buy one of those of you could find it.

Wow, never seen one bofore. I was surprised they are only $500, seems like something you'd have to shell out $1000 for...

I like how the eBay one is listed as "seller refurbished". In other words, he wiped the dust off it... Maybe.

Nice finds! :thumbsup: Learned something new today. Always appreciate the discussion and knowledge on this forum.

I just saw one of these! I was confused for weeks and even told the client it was a code violation. Wow I wish I just opened the panel cover! All because the frame size is too small for the breaker. The bend for that feeder might be a little tight though...
 
6 pole circuit breaker

It's a 3-pole; the QOB3150 & 3175 have this form factor. I want to say the 200/3 and 225/3 take up 12-spaces total, but they wouldn't fit an NQOD panelboard because they go horizontally across the bus on a QO loadcenter.

I changed out a QO loadcenter recently due to a larger pump motor being installed that needed a 125/3, and square d only makes those as bolt-on; the 125/2 comes as a QO snap on though.
