I run two 12V trolling motor batteries in series for my 24V trolling motor.

Decided recently to replace my resettable circuit breakers and ordered two circuit breakers designated as 12 V, 50 amp.  One for  each battery

Distributor sent me two circuit breakers and they were labeled as 24v, 50 amp.

I assume they are incorrect?  If so, what are the ramifications if I use them?

Thanks!.

If you hook the batteries in series you have 24 volts. Even between the batteries you have 24 volts. You have the correct breakers.

You can always use breakers rated for higher voltage in a lower voltage applications. For example. 24v breaker in a 12 volt circuit. You can not use a 12v breaker in a 24v circuit,

Forgive me if I am wrong but you should only need 1 circuit breaker/inline fuse in between the the TM and the power source on the positive lead.

I think your corrrect for a 12V system. I believe my 24V has two breakers, one on each battery.

So long as the batteries are adjacent, only one circuit breaker is necessary.  If they were separated by some significant distance on a metal boat where there is some risk of mechanical trauma to the cables, you might want to install a breaker on each one but it would be rare.

If your system is 12/24 then two breakers - if it is only 12 or 24 volt than one breaker.

With a 12/24 sytem you will have two positive leads and one ground hence the need for two breakers. With a 24 volt system you only have one positive lead hence the need for one breaker.
