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
