I'm thinking of putting a circuit breaker in series with my main positive power wire just in case the controller and BMS went bang, it would be an additional way of saving the battery. I've found this (https://www.carbuilder.com/uk/200-amp-surface-mount-circuit-breaker) which offers the current I would need at a reasonable price but says it's rated for 48v. I spoke to the company and they said they couldn't see an extra 12v doing any harm but obviously couldn't guarantee it. I'm inclined to agree but does anyone know the answer?
Is it ok to use 60v on a 48v breaker?

I guess you could look at it as either 12V over the rating, or 25% over the rating. In either case, I think it will protect your battery, which is the goal. If it actuates, I think the potential issue is frying the contacts from the arcing. Personally, I'd just deal with that if it happens, and maybe carry a piece of wire to bypass it if it happens on a ride, IF I were really worried about it.
