Quiet, practically silent.
I used this on an old oven converted to be a powder coat paint oven. I have about 15-20 hours of use with no problems.

Solid State Relay
Just what I needed all others what twice the price for one piece these came in one package. Took forever to receive. But at least it was cheaper. Still happy

Poor build quality.
Won't stay on for very long before it turns itself off but will then again return for nearly as long then come back on later.

Nice contactor
Exactly what I needed work well however make sure you have a lot of room for it. These are big and bulky with the heat sink

Failed after 5 months.
Control light no longer came on, no water. Installed a mechanical relay till I can find a different one.

How to wire it
Worked as expected relay wise on off indicator lights don’t work but I my case it is inside a sealed case so not a big enough deal to send them back
