Used to connect an inverter to a load while preventing any back feed..I was unsure if this relay had a 100% duty cycle as it would be energized for hours at a time. Happy to find it would run for hours at a time with no overheating. Works well for me and would buy again!!

Excellent quality relay for the price nice mounting bracket. Damage to do to my application negligence. Shows a different style that mounted easier in my enclosure.

It's a relay.I have the AC turning off a switching power supply to a battery with this relay with the AC coil, when AC is dropped, so the battery doesn't feed back into the power supply. A diode would work, but there is less power loss between the power supply and the battery, which makes adjusting the power supply easier, to charge the 12 volt 36 amp battery. This is part of a uninterruptible power source for may server.

These absolutely work and exceeded expectations!

The item was not properly packaged, being in a flimsy plastic bag, rather than protected in an actual box, so three of the anchoring tabs, or " feet", were bent. I was able to straighten them enough to be workable, but this trend toward less packaging has got to stop, else there will eventually come a time when there will be a higher price to be paid for damaged item returns that will cost more than Amazon is saving! Cheaper and lighter packaging, that ends up annoying your customers, is not the answer. The relay does work, though, so far. The coil pulled in at 85 V AC.

I used it to make a latching relay for an electrical outlet. The power goes out and this will keep the outlet out until I reset it.

Bought some 40A solid state relays from amazon thinking it would be more reliable and forward thinking. Wired it up, they locked on without any input voltage (like 20v shy of full power). This is a horrible way to fail (fail off maybe?). Should have trusted the reviews.So decided to just go mechanical relay. Oh look, it JUST works because you can't mess up decades old mechanical design. The description is accurate how to wire it up, but here's an image to clarify. Pins are typical 1/4" male faston so it's easy to add some female connectors to your wires.

It has high current contacts with short wire lengths. I am using for RF high power switching. Excellent quality.
