    The Stainless Steel Sequestr External Disconnect Enclosure package helps mitigate arc flash occurrences when working on interior components by isolating incoming power from the main enclosure. Manufactured from 304 stainless steel, it provides protection from non-corrosive or mildly corrosive elements in both indoor and outdoor environments. A package includes a main enclosure and a Sequestr box. Sequestr  boxes can be ordered separately to retrofit existing enclosures. The disconnect switch and fuse block/circuit breaker are mounted in the external enclosures, with terminal connections to bring power to the main enclosure.
