Have you been caught in the middle of an electrical project and found that you need a weatherproof relay kit (specifically the female receptacle with electrical pigtails and molded plastic covering the underside's leads)?

Problem solved. Here is a Hella-branded SPDT, 30 amp, weatherproof relay kit. The wires that carry the load are 12 gauge. The other leads are 18 gauge.

Order several and have them ready for your next project.

weather proof relay

Used to control two SPAL Fans on my Setrab Transmission oil pre-cooler. With a start current of 4.6 amps and run of 2.8 amps the 30 amp relays provide a robust control circuit.

High quality, great price

Much nicer unit than I could buy locally. Very well made, has tab for mounting wherever you might need it. If you need a sturdy weather proof relay for a project, this is as good as you will find.

I have used a few of these weatherproof relays for wiring up some aux back up lights on a few of our trucks. This relay is stout and designed to withstand the elements that the underside of our trucks are exposed to. Don't settle for the cheap knock-offs. Quality product. Thank you Geno's

There are lots of 5-wire relays out there - most of them are junk. This Hella relay is excellent - well built weatherproof, heavy duty 30A relay. Because it's DT, it provides one normally closed connection and one normally open connection. It's a perfect relay for almost any project.
