TWTADE/JQX-12F-2Z DC 12V Coil Voltage 30A DPDT 2NO+2NC General Purpose High Power Relay 8 Pin (Quality assurance for 1 years)

Using a pre-configured two-wire switch, I needed this to start and stop my MMG55 backup generator during a power outage! When the power goes out, this relay closes and connects the two wires, sending a signal to the generator; when the power comes back on, it opens the circuit and turns off the generator; this was supposed to be built into the ATS, but my ATS doesn't even transfer back to main when the power comes back, but it does start the generator and transfer the power to the generator. Overall, this relay has saved me the trouble of manually sending the signal to the generator from the garage. Despite the fact that the configuration listed in the description does not work, I was able to achieve my goals by using a different configuration.

This relay was purchased to control a 1500W heater that was connected to a G4 remote switch (which was controlled via text messages). (This is fantastic. ) The relays in that remote switch were 10A, and I was worried that putting 1500W through them at 110V would trip them, so I bought this 30A relay to turn on the heater circuit. It's a cinch to use. The clear casing, as others have mentioned, makes it easy to identify the normally 'on' and normally 'off' switch contacts (1 each), as well as the input and output contacts. It doesn't come with instructions, but since you're buying this device, you probably already know how to work with circuits, so the lack of instructions isn't a big deal. If I needed to, I'd purchase another.

For an (up to) 30A automatic transfer switch, it's been working flawlessly for several months. In order to disconnect 120v W/H in my RV power center, I needed buzz/hum-free contactors. When there is no shore power, the converter plus allows the inverter to backfeed, but it must be connected to the W/H. When shore power was present, the converter plus the inverter were disabled/disconnected (after a time delay, shore power was allowed to pass). br>Because these coils are 12 volts, they are quiet while also switching a higher current. During routine inspection, I see no signs of overheating, hot arcing, or welding, despite the fact that the design will eventually fail over to a de-energized state. If this happens, you will be in an energized state. I'm very happy with it.

I'm using it as part of a sump pump alternator, and it failed due to the sump pumps being full of silt; it's not the relay or the application; it's the fact that the crock doesn't have a concrete bottom.

I'm using it to control a pair of pumps; the connection points are solid and hold 1/4" female spades tightly, and I like the clear case because it lets you see what wiring goes where without having to decipher graphics on an opaque case. I have the 120VAC coil model, and it clicks in and out without making a buzzing noise. The relay was mounted to the control box with 1/8" pop rivets.

I'm replacing a 1500 watt incandescent light bulb. The original thermostat on an electric space heater had failed. The Inkbird Temp Control Thermostat ITC1000 is in charge of this relay. The relay can be heard closing and opening, and the relay coil buzzes occasionally.

This relay was used in conjunction with a Hubitat-connected zwave switch. Because Hubitat and Alexa have a partnership, I can now use Alexa to control my pool waterfall.
