Overview

Enhance safety and operational efficiency in industrial environments with the nVent Sequestr External Disconnect Package, SKU A84XD3EW24SSFTCLP. This robust 3-door Type 4X enclosure, constructed from high-quality 304 stainless steel, is engineered to significantly mitigate arc flash hazards when performing maintenance on interior enclosure components. By isolating incoming power externally, it allows technicians to work on sensitive internal equipment with a greatly reduced risk of electrical incidents. The Sequestr External Disconnect Package is designed for demanding applications where reliability and safety are paramount. Its primary function is to house the disconnect switch and fuse block or circuit breaker, effectively isolating the main power supply from the primary enclosure. This external mounting strategy ensures that personnel can safely de-energize the main enclosure without compromising the integrity of the overall system. The terminal connections are strategically routed to bring power to the main enclosure, streamlining installation and integration into existing electrical infrastructure. Manufactured by nVent, a trusted leader in electrical enclosure solutions, this package exemplifies durability and performance. The 304 stainless steel construction provides exceptional resistance to corrosion, making it suitable for both indoor and outdoor installations, even in environments exposed to non-corrosive or mildly corrosive elements. The brushed finish not only adds to its aesthetic appeal but also contributes to its resilience against wear and tear. This comprehensive package includes the main enclosure and a dedicated Sequestr box, offering a complete solution for arc flash mitigation. For facilities looking to upgrade existing enclosures, nVent also offers Sequestr boxes as standalone units, providing a flexible option for retrofitting. The generous dimensions of 84 inches in height, 118 inches in width, and 24 inches in depth accommodate a wide range of disconnect switch and fuse block configurations. Key benefits and features include: * **Arc Flash Hazard Mitigation:** Isolates incoming power externally, significantly reducing risks during interior maintenance. * **Durable 304 Stainless Steel Construction:** Offers superior corrosion resistance for indoor and outdoor applications. * **Type 4X Rating:** Provides robust protection against water and dust ingress. * **Comprehensive Package:** Includes main enclosure and Sequestr box for a complete safety solution. * **Retrofit Capability:** Sequestr boxes are available separately for upgrading existing installations. * **Trusted Manufacturer:** nVent is a globally recognized leader in electrical protection and connection solutions.
