ABSTRACT:
A circuit interruption apparatus for a power circuit having a power source and a load includes a termination mechanism for interconnection with the power source and the load; a circuit interrupter having a line terminal and a load terminal for interrupting the power circuit between the power source and the load; and a pivot mechanism for pivoting the circuit interrupter between a first position wherein the line terminal and the load terminal are interconnected with the termination mechanism, and a second position wherein one of the line terminal and the load terminal is disconnected from the termination mechanism. Alternatively, a circuit interruption apparatus for the power circuit may include a line termination mechanism for interconnection with the power source; a circuit interrupter having a line terminal and a load termination mechanism for interconnection with the load; and a pivot mechanism for pivoting the circuit interrupter between the first position and the second position. Alternatively, a circuit interruption apparatus for a power circuit may include a circuit interrupter having a trip lever mechanism for tripping open the power circuit and for interrupting the power circuit between the power source and the load; and a fuse in series with the circuit interrupter between the power source and the load for interrupting the power circuit therebetween and having a striker pin for engaging the trip lever mechanism and tripping open the power circuit whenever the fuse interrupts the power circuit.
