OK people, cross over electronics, and electrical here. I have a 3Kw immersion heater I am going to control with a a SONOFF smart controller. Now the SONOFF has a 240V output but limited current.
So as I see it 2 options.
Switch a 240C SSR that has a 20A switching capacity or greater
Switch a 240V Coil Relay that again has a 20A switching capacity or greater
Switch a 240C contactor that again has a 20A switching capacity or greater
SSR may have heat issues I assume.
So I see lots of options of contactors, that would work, anyone know if it is an issue, switching something like this many times per day? I like the contactor idea so if it fails it opens, etc.
Any other ideas?
