80A 2NO+2NC

Worked as it should, no problems. Seems to be high quality.

Seems to be a well built product, had a small problem with it and the supplier was great to work with. Use this for charging batteries at an off grid cabin, it's over size for my needs but has robust terminals that I desire. Definitely would buy again if needed.

Edited 01/24/2023 Still working perfectly. System cycles on/off up to 10 times an hour, and has been doing so since October 2022. I'd say this is pretty solid, and well suited for the combined 9000W the water heater takes. Water heater has the thermostatic switch removed, so this is the full wattage/amperage every time it turns on. Still works perfectly.Used this 12V 80A relay to switch a water heater using a Temperature Controller Module also purchased here. The low amperage relay from the temperature controller module powers the coil on the 80A relay, and boom...controlling a pair of 4500W 220V water heater elements is easy.Pretty solid 'click' when the coil is powered up, and a bit of a spark across the contacts, but it works perfectly. The contacts are pretty big, and look to be solid enough to take the amperage, but longevity has yet to be measured. Since this water heater feeds my radiant flooring system in the shop, I expect the relay to be tested to its limit within a few weeks, at best a month before I can tell if it's going to last. File the contacts, and start over if there's a problem.

Good product but horrible packing

Works as designed just a wiring mix up so I updated my rating. The reason the coil was not working because of the wiring was just passing the voltage thru the coil.

This relay appears to be manufactured in one place, in China, under different brand names. I used this to build an automatic transfer switch. This relay appears to be used by a number of different brands of 30 amp automatic transfer switches found on Amazon. I feel that thirty to at most fifty amps should be the limit for this relay, although it is rated for eighty amps. This said, had it running, pulled in, for several hours, it only got moderately warm. I had it in a 6 by 6 by 3.5” enclosure, so I feel that temperature rise is acceptable. At approximately twenty dollars or so, it is a good value. Four of the screws are tucked under other parts of the relay but with a Phillips head screwdriver you can get them tight enough. You also could use a small wrench to get them tighter if needed. The other four are easily accessible.

Worked well to replace worn out contactor in a 2016 Juicebox 40 (not the Pro version, no LED's on the front panel). The only very slight modification I had to make was to very slightly enlarge the mounting holes due to the Jukebox 40 mounting stud diameter. There were other options but this one was the quickest / most available.

I ordered this relay 3 times, and none of them work. When the 1st relay arrived, I wasn't able to immediately install it. A few weeks later when I installed it, the relay wouldn't operate. I checked to be sure I had voltage to coil and did. I removed the relay, ohmed the coil, and it showed "open" on coil windings. It was too late to return this relay, so I ordered another one. I checked the coil winding on the 2nd relay as soon as I received it, and it ohmed open too. Returned the 2nd relay and ordered a 3rd one. Again checked the relay coil when I received it, and the 3rd one showed open. I can't believe this is an Amazon's Choice item when all of the relays arrive defective. Returned the 3rd one and ordered a Dayton relay.
