3pcs 12V Fuse Relay Switch 12 AWG Harness Set with Built-in Diode- 30A ATO/ATC Blade Fuse, 4-Pin SPST Automotive Electrical Relays

Good quality..works like a charm. Installed in my DeLorean...in the AC compressor circuit which does not have a relay, so all the switches need to absorb the electrical load with compressor is being activated...installing the circuit breaker took the load off the now 40 plus year old switches.

Handy to have in the shop! Good price.

Great quality. Makes installations easier with the onboard fuse and very convenient, by reducing wiring.

Color coding could be better. Most others use different colors as standard. Work well, fuses are good quality, build quality is good.

Built in fuse convenient and neater install.

used on a 12v Sureflo R.V. water pump. I got tired of replacing the micro switch in the pressure switch. So now the micro switch turns this relay on and off instead of taking the amperage itself. Working great so far.

Good quality and it arrived on time.

QC isn’t good and you may get a bad relay like I did. Story below if you want more detailsI used the relay for a motorcycle to keep the higher draw off the smaller accessory wires. After putting it all together I verify my wiring and turn the key, no accessories powered. I search out what happened. I had power from the battery to the relay but the coil side blew a fuse. Pop in another fuse with the coil disconnected and had my 12v. Reconnect relay, POP. Swap out the relay with another in the bag, now I have everything working properly. So fresh out of the bag, first relay coil was shorted.
