Abstract
A circuit interrupter apparatus for plug-in connection to a panel board. The circuit interrupter apparatus includes a line terminal for plug-in connection with a line power member provided as part of the panel board, a load terminal for plug-in connection with a load power member provided as part of the panel board, a moveable contact moveable between a closed position, where the line terminal is electrically coupled to the load terminal, and an open position, where the line terminal is not electrically coupled to the load terminal. The circuit interrupter apparatus also includes a sensor module for a plug-in connection to a number of signal conductors provided as part of the panel board. The sensor module detects whether the moveable contact is in the closed position or the open position and output a signal to at least one of the signal conductors indicating a current position of the moveable contact.
