NT90-DC12V-10X Power Relay DC 12V Coil 120 VAC 30A 40A SPDT(1NO 1NC) with Flange Mounting and 10 Quick Connect Terminals Wires Mini Relay(Pack of 2pcs)

Works as expected. Does not overheat like some solid state relays do.

I purchased the 220VAC coil relay. I’m able to remotely read if my well pump is actually receiving 220v by using the relay as the status.

I use one of these with a smart plug to turn on the fireplace with a standing pilot thermocouple gas valve with Alexa. Just unplug the blower and replace with a Smart Plug. Insert a multioutlet adapter. Plug in the blower motor. Mount the relay near the manual on/off switch. Attach the connectors to the relay Normally Open contacts. Attach a 120-volt cord to the relay coil. Set up Smart Plug as "Fireplace" and say Alexa turn on fireplace. This will save you hundreds of dollars. I bought two, one for a spare. Another option would be to wire the relay contacts in parallel so the fireplace can be turned on in a power outage if desired.

Good choice of relays, will order more.

In the picture you will see 2 relays and 5 wires for each relay. What was sent to me were 2 relays with 3 wires total. This relay uses 2 different sizes of spade connectors, Standard width for the relay outputs and narrow for the coil connections. The relays came with only 3 wires, a black, red, and blue wire and all of them had the narrow connectors. Like I said before, it was not 3 wires per relay, it was 3 wires total. This would allow me to connect one of the relays coils but nothing for the relay output connections and not enough wires to even connect the second relays coil, never mind the second relays outputs. What good is a 2 pack of relays if they don't come with the connectors required to use them. I could order or go to one of the big box stores to get the required connectors but why should I have to do that when the image shows it coming with all of the required wires. These will be sent back because as they have come, they are useless without added cost. Sadly, this is an issue when ordering items on-line. You don't always get what you ordered or expected. Fortunately for me, I saw this prior to the return deadline.

The units do what they claim. The signal wires are fine but I would not trust the actual load wires... They are tiny AF for 120vac for 30 or 40 amps. My project was to regulate a 30 amp 120vac generator feed so I crimped my own 10 awg cables to blade disconnect ends. If they provided at least 10 awg load cables this would be 5 stars.
