Trying to find a switch that is strong enough to turn on/off a 50 amp 220V water heater. Any suggestion?
I use The ELK-9200 is a heavy duty relay/contactor rated at 110VAC or 220VAC up to 60 Amps, enclused in a metal cabinet, with plug-in power cord. When 110VAC power is applied to the cord, the relay activates. It can be used with any plug-in automation module to handle high voltage/current applications.
See the following
Very cool advise, very helpful, thanks!
And a fairly recent thread on this topic.
