Automatic dead front disconnect and lockout

摘要

An electrical enclosure that includes a dead front and a lockout switch is described herein. The lockout switch detects the position of the dead front. Based on the detected position of the dead front, the lockout switch actuates a power disconnection mechanism. In one embodiment, the disconnection mechanism is a shunt trip breaker that trips at least one circuit breaker when actuated by the lockout switch detecting removal of the dead front. The shunt trip breaker receives power from a main conductor to a coil that moves a solenoid.

1. An electrical enclosure, comprising:
a dead front; a lockout switch configured to detect a position of the dead front; and a lockout switch arm mechanically connected to the lockout switch, wherein, responsive to movement of the dead front, the lockout switch automatically actuates a power disconnection mechanism, wherein the lockout switch arm is in a compressed position biasing the dead front when the dead front is attached to the electrical enclosure, wherein the lockout switch arm is in a decompressed position when the dead front is removed, and wherein the lockout switch arm moves from the compressed position to the decompressed position in response to removal of the dead front.
