Patent ID: 8130480

Claim:
A resettable circuit interrupting device comprising: an input electrical hot-line connection terminal; an input electrical neutral-line connection terminal; an output electrical hot-line connection terminal; an output electrical neutral-line connection terminal; a resettable circuit interrupter providing at least one of: (a) a first interruptible connection along a first electrically conductive path between said input and output hot-line connection terminals, and (b) a second interruptible connection along a second electrically conductive path between said input and output neutral-line connection terminals; a fault-sensing circuit configured and connected (a) to detect an abnormal current condition of current flowing along said first and/or second conductive paths and (b) to change said at least one of the first and second interruptible connections from a closed to an open electrical circuit condition if abnormal current condition is detected; and a blocking member, positioned in a first position relative to at least one of the first and second interruptible connections to prevent resetting of at least one of the first and second interruptible connections when in an open electrical circuit condition.
