SPDT 120VAC Relay with Mounting Flanges Insulated Connect Wires
120v ac 30amp compact high current relay
This is a well made relay. The small form of this relay and the mounting flanges. It works very well in both NO and NC. AC hooks up to the small terminals. Used this to turn on garage lights from the garage door opener, toggle low voltage fireplace wires driven by AC WiFi switch, Easy to install. if you were hooking up any device you would hook it directly to the relay as if you were hooking up a lightbulb.
Nice and Small, Perfect for Electric Garage Heater / Baseboard Heater Thermostat Conversion / controlled multi speed fan
If you were hooking up any device you would hook it directly to the relay as if you were hooking up a lightbulb. You would hook up AC POWER ON THE SMALL CONNECTORS ONLY the Black on one small connector and White wire on one small connector in any direction on the small terminals that will activate the magnetic coil. Hooking up the AC power to the small terminals directly will not short out the relay that is designed to receive AC power.
Perfect mount it behind the light switch in the wall and used the available 120 volt light source to active the relay with then turns on the fireplace. Command the fireplace to turn on your using Alexa for the light switch, and quiet when switching.
Easy to install, Multi-purpose
Easy to install and small wire pigtails are included for easy connection. Good size. Use the relay to disable the compressor on your beverage cooler during on peak hours.
Epoxy Sealed Versions Available
Small totally encased high current relay with push-on connectors. Connections are recessed so very little metal is exposed. Coil contacts are smaller push-ons to help prevent wiring confusion.
Safe and Durable
Small and perfect relay.
Epoxy sealed could be more rugged, perfect for your application style (inside a control box)
The contact connections use 1/4" fastons, and the relay coil uses 3/16" fastons. While not as popular as 1/4" fastons, these are not 'non-standard'. Most hardware stores carry what you need.
AC hooks up to the small terminals
PROS:
AC connector is the small terminal connectors for people that are confused.
1.Other connectors on the relay when the relay is not energized with the AC power the connectors inside will allow power to go from the COM connector to one terminal that is large.
2.When the AC relay is energized the connector inside the relay will allow the COM connector terminal that is large to go to the other large connector.
3.The AC connector that is small does not pass any power to the large connectors at all they are isolated from each other. Using the large connectors is an open and door circuit That you choose to allow power to pass through in the closed position when the AC power is energized on one large terminal connection and when the AC power is turned off it will allow the power that is hooked up to it to pass through the other side. Again these two AC small connectors are only AC power only to energize the Relay only.
4.On the COM connector, you hook up the positive DC and you choose the other large connector if you want the power to come out when the AC power is on will allow one LARGE terminal to be active, and when the power is turned off to allow the DC power to go through the other LARG terminal that is large completing your connection circuit.

I had to activate a low voltage fireplace gas log selinoid with a 110v smart switch.Works great

I used this to turn on my garage lights from the garage door opener, works great but I didn't use the included leads as the wire guage was too small for my application, the relay functions as expected with my heavier wires. highly recommend.

I used these in conjunction with Kasa HS200 switches to make our gas fireplaces wifi enabled. I love hearing the relay click when I ask Alexa to turn on my fireplace!

This is the second relay I bought. This time they included wire pigtails with proper spade connections. The first one did not. The two spade connectors that power the relay coil are miniature spade connectors that are not usually available from local DIY sources, and that leads to installer compromised connections,frustrations and wasted time looking for miniature spade connectors.This time it was easy

**** Update ****I'm using this relay with a switch & breaker as a "shut off" for my battery box. Initially I limited the charging to 4 amps (4 amps through the relay) and there wasn't an issue with the relay getting hot. Later on I used a 10amp charger and found the relay got noticeably warmer (note this relay is rated for 30amps). When I got around to using a 20amp charger (which hit an actual maximum of around 17amps) the relay became hot, particularly right at the main power spade connections (the 14awg wires were only slightly warm). The relay didn't melt, or anything like that, but I do feel like 10amps is the most I'm comfortable putting through this "30amp relay". For the very short (less than 2 ft) runs of wire, the 14awg wire I used should be adequate; still I'm going to increase the main wires to 10awg since my expectations for the battery box have increased. I'm beginning to wonder though, if a "30amp relay" shouldn't have terminals larger than 1/4" spade connectors to carry 30amps.**** Original ****The relay was received damaged, see photo. I tried an epoxy repair, but it didn't hold (I may make another attempt at this). I'd like to have the relay attached to something, but it's light enough that I suppose it could be held in place against the wires with a wire tie or two.I tested the relay and it functions properly. What I don't care for are the small size spade connections for the coil terminals. I realize the coil connections don't carry any significant current, so larger connections aren't needed, however I have plenty of the normal size spade connectors and none of the little size. I got some from a friend, but they have a plastic coating on the outside and don't fit in the opening. I may try shaving off some of that coating, but it seems an unnecessary trouble just to save a tiny amount on the size/weight of the relay.
