Overview

Enhance safety and operational efficiency with the nVent Sequestr External Disconnect Package (SKU: A72XD4018SSFTCLP). This robust Type 4X enclosure system is engineered to significantly mitigate arc flash hazards by isolating incoming power from main electrical enclosures. When maintenance or internal component work is required, the Sequestr package allows for safe de-energization without compromising the integrity of the primary system. Constructed from durable 12-gauge Type 304 stainless steel for the main enclosure and 14-gauge for the Sequestr disconnect enclosure, this package offers superior protection against non-corrosive and mildly corrosive elements. Its brushed finish not only provides an aesthetic appeal but also contributes to its resilience in demanding indoor and outdoor environments. The Sequestr External Disconnect Package is ideal for applications in industries such as food and beverage, packaging, water, petroleum, and chemical processing, where reliable and safe electrical management is paramount. This package is shipped as a single unit for seamless installation in new projects. It integrates the disconnect switch and fuse block/circuit breaker directly into the external Sequestr enclosure, with terminal connections designed to efficiently route power to the main enclosure. For existing installations, the Sequestr enclosure can be procured separately to retrofit into compatible main enclosures, offering a flexible upgrade path. Key Features and Benefits: * **Arc Flash Mitigation:** Isolates incoming power to enhance safety during internal enclosure maintenance. * **Durable Construction:** Manufactured from 12-gauge and 14-gauge Type 304 stainless steel for exceptional corrosion resistance. * **Type 4X Rating:** Provides robust protection against water and dust ingress, suitable for harsh environments. * **Versatile Application:** Designed for use in food and beverage, packaging, water, petroleum, and chemical processing industries. * **Integrated Solution:** Shipped as a complete package for new installations, including main and Sequestr enclosures. * **Retrofit Capability:** Sequestr enclosures available separately for upgrading existing systems. * **Industry Standards Compliance:** UL 508A Listed (Type 3R, 4, 4X, 12), cUL Listed (Type 3R, 4, 4X, 12), NEMA/EEMAC (Type 3R, 4, 4X, 12), IEC 60529 (IP66), and meets NEMA Type 3RX requirements.
