Contactor coil current rating
WebAug 15, 2024 · For the relay to work mechanically, the ampere-turns of the different coils has to be about the same for different rated coil voltages. So the DC resistance of a 5V coil will be less than for a 12V coils. Relays are basically current-operated devices that are specified in terms of voltage.
