Abstract: A latch system for an electrical equipment enclosure includes a chassis and a latch arm, engaged with a circuit breaker, that moves between first, second, and intermediate arm positions. A handle operatively connected to the circuit breaker is movable between ON, TRIP, OFF, and RESET handle positions. The handle is operatively connected to the latch arm such that the latch arm is positioned in the second arm position when the handle is located in said RESET handle position. The latch arm spring biases the latch arm into the first or intermediate positions when the handle is in the ON, TRIP, or OFF handle position. A lockout plunger is connected to the handle to rotate with the handle and is movable between disengaged and engaged positions. The lockout plunger prevents movement of the handle from the OFF to the ON handle position when the lockout plunger is in its engaged position.

Abstract: A latch system for an electrical equipment enclosure includes a latch arm receiver adapted to be connected to an associated enclosure door. A latch arm assembly is adapted to be connected in operative engagement with an associated circuit breaker. The latch arm assembly includes a chassis and a latch arm that moves relative to the chassis between: (i) a first arm position; (ii) a second arm position; and (iii) an intermediate arm position between the first arm position and the second arm position. A latch arm spring biases the latch arm toward its first arm position. A handle is rotatably connected to the chassis and operatively connected to the toggle of the circuit breaker. The handle is movable to and between an ON handle position, a TRIP handle position, an OFF handle position, and a RESET handle position. The handle is operatively connected to the latch arm such that the latch arm is positioned in the second arm position when the handle is located in said RESET handle position. The latch arm spring biases the latch arm into one of the first position and the intermediate position when the handle is in any one of said ON handle position, said TRIP handle position, and said OFF handle position. A lockout plunger is connected to the handle to rotate with the handle and is movable between a disengaged position and an engaged position, wherein the lockout plunger prevents movement of the handle from the OFF handle position to the ON handle position when the lockout plunger is in its engaged position
