I put about 23 amps through this when running my 240V, 5500 watt heater element in my brewery setup. It runs nice and cool with a heatsink and a fan blowing across the heatsink. Switches on and off perfectly. The terminals are solid, hold anything from a small spade connector to bare 10 ga wire just fine, (and can probably take much bigger wire). It's a nice, sturdy little component.

This relay is exactly as pictured, the Fotek SSR-40 DA. It has a metal backing plate, but a matching metal fin heat sink is sold separately.

It's very easy to drive, and I've had no problem driving it with 5V and sinking the current through a microcontroller. No driver required for an Atmega328P.

After about two years of extremely light, intermittent use, this relay has died on me. Regardless of input (open or closed), and regardless of the LED status light, the output circuit is always closed, causing the connected device to run continuously. Things fail, but if this thing fails, and whatever you have hooked up to it can't run indefinitely, you have a real problem.

I use this as a switch to turn on the Porter cable router and vacuum for a homemade CNC routing table.
Works flawlessly and highly recommend.

I bought this item so that I could use low voltage control to enable and disable my oil-less air compressor. It is easy to install. My air compressor draws about 16 amps at 120VAC single phase. So far this solid state relay is performing as expected.

It does say it needs a heat sink. My air compressor only runs for maybe a minute or two at a time, so I haven't noticed any appreciable heat output from this device. I used some heat sink goop on the back and simply mounted it in a 4" square metal electric box that had a smooth back; that seems to give it a bit of heat sink.

I used a spare 4.5VDC cell phone charger with the end cut off as the DC supply for control voltage. It seems to be working fine.
