Abstract
An apparatus includes an energy storage module that receives power from an AC power source. The energy storage module is sized to store electrical energy received from the AC power source that is sufficient to open one or more contacts when the AC power source is not present. The contacts disconnect electrical power to a load and the electrical energy is stored in a DC energy storage device. A connection module connects the energy storage device in series with a trip contact, a trip circuit, and an auxiliary contact. The trip contact closes in response to a trip signal. The trip circuit disconnects the one or more contacts in response to being energized, and the auxiliary contact opens in response to opening of the one or more contacts and disconnects power to the trip circuit. A disconnect module periodically disconnects electrical power from the trip circuit and the auxiliary contact.
