Abstract text

A circuit interrupter trip apparatus operably connected to an operating mechanism of a circuit interrupter includes a sensor and a switch operably connected and responsive to the sensor. The switch is positioned such that the sensor changes the operating state of the switch in response to detection of a predetermined electrical condition, such as an electrical fault. A controller is operably connected to the switch and is configured to activate the operating mechanism in response to a change in the operating state of the switch.
