APIELE 4 Pin Relay 12V 40A With 30A Fuse DC SPST Fused Normally Open 1NO With 14 AWG Harness Socket for Car Truck Motor

Works well for what I needed it for... Needed it for trailer lights Installed on my Harley...

I used this relay to wire into my tractor that was having starting issues. I took the 12v (which was only 10.5v by time it reached the solenoid) and used the relay to jump a fresh 12V to the starter. Worked perfect. I like how the relay has a built in fuse and screw mount. Also the wire leads were a good size. Great relay for any project.

Purchased this relay to fix a no start issue that is common on Kohler garden tractor engines as they age. The relay works perfectly and the built in fuse is a nice touch and looks cleaner than installing an in-line fuse, which is why I purchased this relay in the first place. For anyone with a click when they turn the key on your Kohler engine this is a good fix and will not remove any of the safety features of the tractor. I’ll include a picture of the wire diagram that I obtained on a tractor forum.

I like the relay and the wiring. harness. I would have given the item a five star rating but the schematic that was shown in the description is incorrect. It shows that the fuse protects both the control switch and the device circuits. The fuse only protects the device, a second fuse must be installed to protect the control switch.

got 2 of these to wire up a light bar and a future accessory on my Tacoma.super convenient to not have to add a fuse.this is 30A and Not 40A but it is more than plenty for a 30 inch led light bar

Use these relays all the time to isolate hybrid Network regulators we fit on motor vessels. The integral fuse makes for a neat installation.

Relay worked properly for about 2 days. It is stuck in the on position.

They seem to be good.I wish the wires would have been a little longer.…and, when the did the "pre-strip" of the insulation they did it WAY too long...I would say close to a full inch.
