Breaker for 12v and 240v

[Uniopp]

Is there such a thing as a double breaker that has a separate DC and AC line passing through it?
I need a 12v (25 amp) line and a 240v (15 amp) line that if one is tripped the flow on both lines will stop.
I’m using it for a 240v (15 amp) marine air conditioner that requires a 12v (25 amp) water cooling pump running at all times the air conditioner is running. I want one breaker switch that turns them both on/off together and will trip if something goes wrong on either line.
The purpose of both being on the same breaker is so one can’t run without the other - one switch controls power to both.
I would appreciate the correct name/model number of what I have described above (or a more suitable suggestion if better).
Thanks

A flow switch on the water cooling line that prevents the compressor from starting if there is no flow would be my suggestion.
it will also shot the ac down if the pipe becomes blocked or the heat exchanger freezes.
