ABSTRACT:
A multi-coil automatic transfer switch (ATS) adapted for automatically switching an appropriately rated component to render the ATS operational over a worldwide voltage range is provided. A low voltage contactor includes a low voltage coil magnetically linked with a normally open low voltage main contact. A high voltage contactor is coupled in parallel with the low voltage contactor. The high voltage contactor includes a high voltage coil magnetically linked with a normally open high voltage main contact. A normally closed high voltage auxiliary contact is magnetically linked with the high voltage coil. The normally closed high voltage auxiliary contact has a phase opposite the normally open high voltage main contact. The high voltage contactor opens the normally closed high voltage auxiliary contact to disconnect the low voltage coil.
