Abstract

A disconnect feature is provided for a circuit interrupter that is conveniently incorporated with the circuit interrupter. The disconnect feature is operable between closed and open positions, providing a visible open gap in the open position. The disconnect feature includes a pivotally mounted contact arrangement that is supported with respect to the circuit interrupter. The pivotally mounted contact arrangement cooperates with an interengaging contact carried by a contact terminal of the circuit interrupter. In specific arrangements, interlock features are provided to disable operation of the circuit interrupter when the disconnect feature is moved out of the closed position. In one arrangement, the disconnect feature is blocked from operation until the circuit interrupter is operated to an open circuit position.
