Is there a fuse relay?
In the fuse box on a modern car, you’ll find a whole bunch of multi-colored electrical fuses and larger, plastic boxes called relays. Fuses are included on all your car’s various electrical circuits to protect components from surges of electricity. Relays are remote switches that open or close an electrical circuit.
Do you fuse before or after a relay?
It could be conceivable that the relay could get an internal fault and short the live feed to ground. If you put the fuse after the relay, then that internal short would mean that the live wire from the relay to the battery is not protected. It could then melt and cause a potential fire risk.
Why we Cannot use fuse instead of relay?
The conventional relay usually consists of an electo-magnet, and an armature which operates contact points. A fuse is purely intended to burn out should it become overloaded, thus protecting the rest of the circuit. A fuse cannot operate as a relay as such.
