I am using a PCB mounted DPDT relay rated at 1250VA at 250VAC, to switch a 1KW 250VAC immersion heater on and off, and which (the relay) has failed after a couple of weeks of use.
(The coil still actuates, but one of the contacts does not throw)
It is simply wired 250VAC to both common contacts, and the purely resistive load wired across the normally open contacts.
Should I have included something to protect the contacts, like a capacitor?
The relay is a Maplins **broken link removed**
