I’ve posted it before but this is what happens when you put 230V through a 110V coil. The coil voltage was applied whenever the machine control was on, so it would easily be sitting at the over voltage for 8 to 10 hours a day. I think it lasted three days before failing.
Physically the contactor looked fine, but you couldn’t manually push the contacts together like you should be able to.
Always always always check the coil voltage as well as the contactor rating, don’t just rummage around the parts cupboard for something that looks similar!
