Abstract
An explosion absorbing apparatus for use with circuit breakers mounted in an explosion-proof panelboard enclosure includes force absorbing plates and rods for attaching the plates to the side panels of circuit breakers. The fastener members draw the force absorbing plates together against the side panels of the circuit breakers to absorb the stress generated by an explosion inside the panelboard enclosure. This apparatus ensures the integrity of circuit breakers contained within a panelboard enclosure during an explosion. The force absorbing plates eliminate catastrophic destruction of the circuit breakers and reduce the cumulative explosion pressure in the panelboard enclosure.
