Solid State Relay for 220 volt single phase motor

[Cncmachine2]

Currently using a solid state relay with input 3-32 VDC, Output voltage 24-380 VAC and Output current 25A to power on/off 1 HP 110 volt electric motor. The current relay has only one connector for the 110 volt input and load side wire. I want to upgrade motor to a 3HP 220 volt . Any thoughts on a solid state relay which will work for this 220 volt application? Can I add another relay and use in parallel?

That Fotek relay can be used for 220VAC ?

You could use 2 of those to switch both sides of the 220 line. I have not seen a single solid state relay with two line and load terminals.

You could use a contactor.

how about a dual SSR



basically two solid state relays in one package


for 3 phase motors you have these 3 phase SSR's




3 Hp is only 2.2Kw so at first sight a 25A rely will be OK
but you need to have a relay that can withstand the start up current

just beware from places like ebay some of the solid state relays are fake !!!

Yes most manufacturers make them, I have used them many times, they are normally expensive but here is a cheap one and a more expensive one


Holdwell Dual Solid State Relay SSR 17-32VDC Input 280VAC 40A Random or a Crydom D2440DE-10

Cool, never really looked for one before. Good to know.
