40 amp SPST with built-in fuse, included
The easiest way to add a power circuit that we’ve ever seen. Just wire the relay between power and the load, add a control switch to trigger the relay and one ground wire… you’re done! No need to wire in an extra fuse holder, no problems because all of your fuses are already used. And it’s really neat, compact and clean. Size the fuse to your load requirements and the circuit is protected.
