Abstract
An electrical system includes a contactor having a pair of contacts and a coil configured to electrically close and open the contacts. The electrical system also includes a high voltage ('HV') circuit including a power supply electrically connected to at least one of the contacts of the contactor. The electrical system further includes a low voltage ('LV') circuit electrically connected to the coil and configured to selectively energize the coil of the contactor. A disconnect mechanism is coupled with the LV electrical circuit and operable to electrically open the LV electrical circuit to actuate electrical opening of the contacts of the contactor.
