Be aware, that may not be a simple circuit breaker. It is more likely a galvanic isolator. Check it online to learn what they do.

Its a 30 A breaker and an ELCI or a GFCI. It is protecting the inlet power to the boat.

I'm pretty sure all ELCIs are 2 pole breakers because they must break both the Hot (black) and Neutral(white).
They must be within 10 ft of the shore power plug.

The OP picture looks like a single pole breaker but it has a TEST button. Thats confusing me.

The Galvanic Isolator only connects to the inlet Green ground wire.

yeah. galvanic isolators are a bit larger now as far as i know. you may not get the exact breaker, but they are available. agree that you need to verify the galvanic isolator aspect. ron
 
one more thing. if you haven't been in there for a while, be ready to replace some of the wire runs if they show signs of corrosion
 
belay the isolator comment. that pic looks like the grounds going to the isolator. you should still verify corrosion issues with them and the isolator itself.
