description Method and apparatus for sealing an air vent in a switchgear cabinet provide a vent seal assembly having a vent seal cover and a set of linear guides on which the vent seal cover may be mounted. The vent seal cover and linear guides are housed within a casing attachable to an interior surface of the switchgear cabinet and directly over an air vent. Within the casing, the vent seal cover may slide freely along the linear guides toward the air vent, with no spring or other mechanical biasing mechanism to oppose the sliding of the cover. A catch on the casing releasably holds the vent seal cover to keep the air vent open during normal operating conditions. When an arc event occurs, pressure from the arc event knocks the vent seal cover free of the catch and propels it toward the air vent, quickly slamming the air vent shut.
