In a magnetic motor starter, when too much current comes through the circuit, the heaters are supposed to get hot, and openn the contacts, thereby stopping the motor and preventing it from burning itself up.
Are the heaters reusable after they cool down? Or are they like a fuse, once they've blown, thats it, get new ones.
In particular I am curious about a Furnas magnetic motor stater on a 3 HP early 1970's unisaw. The starter takes Furnas E-52 heaters for my particular motor at 230 volts.
Thanks in advance.
