Blown Breaker Compatibility

[Rhoadzie]

I finally found a breaker on the frame of my 27rr that had blown. I went to a local RV dealer and they gave me a 12v 30A breaker. But the one that came off was a 24V 30A breaker. So are they compatible?

Yeah they're compatible. The amperage rating is the main factor.

Did it look similar to this one?



The reason I ask, is that these kind have a reset button on them. See the little black button, near the bottom...you usually can just press this in and reset the breaker if it's tripped.

Though you are replacing the breaker, has the source of the cause been found and eliminated?

You say it was blown. They are resettable, did you try resetting it.

As Bama said... amperage is the important factor here.

Voltage really only comes into play when you exceed the voltage rating of a circuit breaker.

With that said, it is not uncommon to use a 24v/30amp CB in a 12v system so replacing it with a 12v/30amp CB (in that same 12v system) is no problem. It is still rated for 12v.

I would not suggest using a 12v/30amp CB in a 24v system.
