The ProLine G2 Sequestr External Disconnect helps mitigate arc flash occurrences when working on interior components by isolating incoming power from the main enclosure. The disconnect switch and fuse block/circuit breaker are mounted in the external enclosure, with terminal connections to bring power to the main enclosure. The ProLine G2 version of Sequestr functions in an analogous sense to nVent HOFFMAN’s namesake Sequestr product, but is designed and manufactured on a full-height ProLine G2 frame to seamlessly integrate.
