Fusing emergency brake wire

I installed an emergency brake-away switch on vintage trailer I was rebuilding, it did not have an emergency brake-away switch before. I debated as if you really want/need a fuse between the battery and the emergency break-away switch. My normal rule to fuse every lead on the positive side. But it seems that if that switch is activated for real you do not want a fuse to pop and deactivate the brakes at that moment. But after thinking about it more I'm not so sure of that idea. If the emergency switch is activated in a non-emergency case I might want it fused. I figure if the emergency brake is activated then the safety chains have also broken and the trailer is back there doing its own thing. Any opinions on this and what size of fuse/breaker is typically used for standard electric brakes on Dexter 3,000 lb axles?

I've never seen the trailer brake, break away system fused; on any of the 4 5ers I owned or any of the TTs I worked on. But if your really worried about it , install a 40 amp self resetting 12 volt circuit breaker.

No fuse. If that thing is activated you need it to work no matter what, could be the end of the TT. If it's activated on accident that's your fault.

The main concern is if the wire from the battery to the switch becomes shorted some bad things could happen. I would just give that wire extra protection.

no fuse is more common

a 40 amp resetting circuit breaker ...

and the wire size , even with a dead short. will not start a fire.. just melt wire.

Thanks for all responses. I'll stick to the no fuse solution.

My 2016 Coleman has a self resetting 40 A circuit breaker. Hopefully I will never have to really try it out...
