If You Need to Switch More than Ten Amps, Check This Out.
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.

Works as Designed
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.

Worked to repair EVSE Charger Juicebox 40 (2016 -- 12V DC coil version)
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.

Misleading documentation
I had to order two relays to find out it requires 110 VAC to the coil for it to function. Testing the coil with an ohmmeter shows it to be open (infinite resistance). I also tested the relay using 24 VAC and 12 VDC on the coil terminals. The specs seemed to indicate these options should have worked. So I returned the original for a replacement.The replacement exhibited the same characteristics as the original. Finally, after scratching my head and carefully re-reading the specs, I had an aha moment. When I connected 110 VAC to the coil it transferred solidly. I can't report on the actual usage yet--I still must assemble the control circuit. However, at this point it looks like I have what I need. I'm guessing there is an internal capacitor in the coil body which rendered the open measurement with the ohmmeter.

A HAPPY CAMPER
Came in a plastic case which is not shown. This makes the relay dust free. A wonderful extra.

So far, so good
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.

Relay Doesn't function
Relay arrived with a broken base corner. I needed to place my equipment back into service, so I epoxy repaired the relay base. ( I considered this a shipping problem) With the relay installed, it failed to properly function. The coil does operate, however not enough to latch the contacts into place, Voltage applied to the coil was validated to be12.8 vdc. Polarity of the 12.8 DCv was reversed and the relay tested again. The relay still did not pull the contact arm enough to connect the contacts. I cannot return the product because of my epoxy repair. That's on me. My repair had nothing ro do with the relay arm and coil not functioning. That's on the manufacturer.
