Using this product in a circuit for ten plus years, and performing flawless. A new project will get the same quality, highly recommend.

Used as slave controllers for Lowell sequencer system. As always worked great!

I was only running 20A through this relay, half the rating. It hit 250 degrees and started to melt. Definitely a fire hazard. I should not have mounted it on wood which acts as an insulator, and also should have used a heat sink. I had no idea they would get this hot.Just be aware.

They work great. I added heat sinks, just in case.

These relays were used to control a 120V 20A resistive load. They are rated at 40A. The load was limited to about 30% duty cycle by a cycle timer and good heat sinking and fan cooling was provided. On the initial use they suffered a simultaneous catastrophic failure. The relays exploded in their enclosure.Before and after pictures attached.

So far so good, although I am still testing these units.

Just what I needed. I needed an ac to ac relay and these worked perfectly. Used them for a floor heat system where the thermostats were 24 bolt ac and the pumps were 120.

Noting bad to say so far. They power my smartified furnace fan and work reliably everyday since.

Wired this up to run my router vac whenever I turned on the cnc router spindle. No issues at all. I would recommend it.
