Review: Have had no problems
Review: This is a very fine relay, well made and high quality. I bought it to use for a car electrical project, where I needed it to work reliably without any worries. Most of the automotive relays you see here are cheap no-name relays with no specs, and frankly, I wouldn't trust them to work reliably for an important purpose. The Hella relay has a very complete spec sheet that you can find on the internet, if you search for Hella plus the part number. The coil resistance is spec'ed at 85 ohms, I measured 86 ohms for my relay. The pull-in voltage is spec'ed at less than or equal to 8.0 volts, I measured 7.65 volts. The drop-out voltage is spec'ed at greater than or equal to 1.0 volt, I measured 2.8 volts. The other specs are impressive and believable. The relay is slightly on the large size, so you will need a decent amount of room to mount it, especially if you use the very nice Hella wiring harness that I also purchased and have reviewed (Hella part number H84709001). With the Hella harness, I can believe that the connection is "weatherproof" as specified, but only if you mount it right-side up. If upside-down, water might still leak into the connection somehow. The Hella relay is more expensive than the cheapo generic relays, but you certainly get what you pay for in this case. The relay installed and worked just fine for my purpose, and I was very satisfied.

I’ve over amped these but never had one fail from water ingress. Good product for those places that get a bit moist.
