Door-Closing Mechanisms

Class 9423 door-closing mechanisms may be used on enclosures with door openings up to 91 inches. The door closing mechanisms are designed to be used on control enclosures and interlocked with a Class 9422 disconnect device, although they all can be used independently. Three different systems are available. A complete system is available for interlocking all the doors of a multi-door enclosure with the master door when using the 6" or 8" vault handle mechanism.

The “Master Door” is defined to be the door of a single or multi-door enclosure which is interlocked directly with the disconnect device. The master door can be hinged on either the right or left hand side. It can be located in any position on a multi-door enclosure. The “Auxiliary Door” is defined to be the remaining door(s) of a multi-door enclosure which is (are) interlocked with the master door by means of the overhead interlocking system.
