I have a relay that is switching 240V supply to a plug pack. The plug pack in turn supplies 24V to a solenoid coil.
The relay has fused in the closed position and I'm trying to figure out why and the best way to protect it when I get a new one.
Am I correct in assuming the flyback from the solenoid is isolated by the plug pack?
And if so, will an RC snubber circuit be the correct way to prevent arcing when cutting supply to the plug pack?
The relays specs can be seen here: link
It's rated for 6A 250VAC and is switching a 0.9A plug pack.
