Each BRAKE MAGNET draws 3AMPs EACH with 12VDC applied. Two wheels is 6AMPS - Four wheels is 12AMPS... When your break-away switch is activated it will provide a full 12VDC from your TRAILER BATTERY to all of the connected BRAKE MAGNETS.
Looking at two or three installation guides online including ETRAILER.COM I didn't see where a FUSE was installed in-line. However the battery is capable of alot of power being developed during a short circuit. A couple hundred AMPS probably - maybe more. A short circuit will definitely melt your break-away switch wiring and we have seen that reported on here... A wiring catastrophe fuse would eliminate this from happening. I don't think my wiring has any in-line fuse involved.
Probably your call whether or not you want one installed.
