    Abstract: An automatically operating interlock prevents connection of an electrical device within a cabinet unless the cabinet door is closed. The interlock is particularly useful for circuit breakers contained within arc-resistant cabinets. The interlock includes a spring-biased locking plate reciprocating between a locked position wherein the locking plate resists movement of the levering-in locking plate, and an unlocked position wherein the locking plate permits movement of the levering-in locking plate. The locking plate is spring-biased towards its locked position, and is pushed from its locked position to its unlocked position when the cabinet door is closed. Access to the hex drive of the levering-in rod is thereby resisted when the cabinet door is open.

    Abstract: A switchgear cabinet includes a plurality of securing apparatuses that are mounted on a vertical flange of the switchgear cabinet, with the securing apparatuses each being formed with a locking hole that is engageable by a pin of a locking mechanism on a door member. Each securing apparatus includes an anchor plate connected with a first bracket and a second bracket, with the first and second brackets being mounted on the flange of the switchgear cabinet. The locking hole is formed in the anchor plate, and the anchor plate is substantially planar and free of bends. The anchor plate further is generally U-shaped and is configured to extend generally around at least a portion of the flange.
