3 phase circuit breaker

[thaeni]

The photo is a I believe a 3 phase circuit breaker. Any ideas on where to locate. I tried West Marine, Home Depot, Lowe’s, Amazon, Hunter store no luck. It’s from a 1992 Hunter 33.5.
Thanks

What in the world do you use 3 phase power on a 1992 Hunter 33.5? Are you electric powered? 3 phase power is used to power large motors and other heavy loads.

Well, that was my first thought too. But who knows. I think what he wants is a double pole breaker, which in household wiring is for 220 or 3 phase.

Same question popped into my head as I read the post.

I think Dave has deciphered the challenge.

What you may have is a combination of circuit breakers and “reverse polarity” detector.
These have three individual blocks ganged together :
One disconnects live on high current
One disconnects neutral on high current
One detects high voltage between neutral and ground and trips if that occurs.

If any one of these conditions occurs the whole gang trip together.

Double pole not for 3 phase... for 220 single phase which could be split phase (110) to the neutral.
I cannot fathom any boat smaller than a massive workboat or a cruise ship having 3 phase power.
3 phase breakers are big.. (image stolen from some stock image site):
