Great AC relay for projects
I needed an Alexa-enabled heavy duty relay, and nothing really exists to switch heavy loads. Don't believe manufacturers who say theirs can switch large motors and such - reviews will show melted switches. So, I decided to build my own, using this relay to switch the heavy load - 15A, but a large inductive (motor) load. This appears to be a really nice, heavy-duty relay, and seems to work well. I removed the spade lugs on the switched relay connections as I'm only switching one outlet, and prefer direct connection to 14 gauge copper. I did use the spade lugs for the relay coil connection, with a Tapo Alexa-enabled smart switch driving the coil power. Then, put it all in a metal box (see photo, sans cover). For the smart switch, one nice feature of the Tapo switches is that you can set them to be normally off, so after a power outage, the switch will remain off until turned on - the switch default is to remember the last power state.

Great price good quality
I’m really pleased with this SunLee contactor. It was a direct replacement for my old unit and installed easily in my HVAC system. The contacts feel solid, and the unit has been working quietly and reliably so far. Great value for a 40 amp contactor—no issues after weeks of use.”
