Abstract
An automatic transfer switch and protection device is provided. The device includes a contact, a drive assembly, and a controller. The contact is movable among a first position, a second position, and a third position. The drive assembly moves the contact among the first, second, and third positions. The controller receives a first signal indicative of a condition of power in a first power source and a second power source. The controller provides a second signal to the drive assembly to move the contact in response to the first signal. The contact can provide power to a load from the first source in the first position, from the second source in the second position, and can isolate the load from the first and second sources in the third position.
