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.

L'invention porte sur un commutateur de transfert automatique (ATS) à bobine multiple conçu pour commuter automatiquement une composante de valeur nominale appropriée afin de rendre l'ATS fonctionnel sur une plage de tensions mondiales. Un contacteur basse tension comprend une bobine basse tension liée magnétiquement à un contact principal basse tension normalement ouvert. Un contacteur haute tension est couplé en parallèle au contacteur basse tension. Le contacteur haute tension comprend une bobine haute tension liée magnétiquement à un contact principal haute tension normalement ouvert. Un contact auxiliaire haute tension normalement fermé est lié magnétiquement à la bobine haute tension. Le contact auxiliaire haute tension normalement fermé a une phase opposée au contact principal haute tension normalement ouvert. Le contacteur haute tension ouvre le contact auxiliaire haute tension normalement fermé afin de déconnecter la bobine basse tension.
