Overview

Enhance safety and operational efficiency in industrial environments with the nVent Sequestr External Disconnect Package (SKU: A90XD7820SSFTCLP). This robust solution is engineered to significantly mitigate arc flash hazards when performing maintenance or adjustments on interior enclosure components. By providing a secure external isolation point for incoming power, it effectively separates the main power supply from the primary enclosure, allowing personnel to work with greater confidence and reduced risk. The enclosure is meticulously constructed from high-quality 304 stainless steel, a material renowned for its exceptional resistance to corrosion and its durability in both non-corrosive and mildly corrosive atmospheric conditions. This makes the Sequestr package an ideal choice for a wide array of applications, including chemical processing plants, food and beverage facilities, wastewater treatment operations, and general manufacturing settings, where environmental resilience is paramount. Its Type 4X rating ensures superior protection against water and dust ingress, safeguarding sensitive electrical equipment from the elements. Each Sequestr External Disconnect Package includes a main enclosure and a dedicated Sequestr box, designed for seamless integration. The disconnect switch and fuse block or circuit breaker are conveniently mounted within the external Sequestr enclosure. Terminal connections are strategically placed to facilitate the efficient transfer of power to the main enclosure, simplifying installation and wiring. Key benefits and features include: * **Arc Flash Mitigation:** Dramatically reduces arc flash risk by isolating incoming power externally. * **Durable Construction:** Manufactured from 304 stainless steel for superior corrosion resistance and longevity. * **Environmental Protection:** Type 4X rating provides robust defense against water and dust. * **Integrated Solution:** Package includes main enclosure and Sequestr box for a complete system. * **Flexible Retrofitting:** Sequestr boxes are available for separate purchase, enabling retrofitting of existing enclosures. * **Simplified Maintenance:** Facilitates safer and more efficient access to interior enclosure components. This package is particularly valuable in industries where downtime is costly and personnel safety is a top priority. The ability to isolate power externally means that routine inspections, component replacements, or troubleshooting can be performed without exposing workers to the inherent dangers of live electrical systems. The 90x78x20 inch dimensions offer ample space for standard disconnect and protection devices, while the two-door design of the main enclosure allows for convenient access and organization of internal wiring and components. nVent is a globally recognized leader in electrical enclosure solutions, known for its commitment to innovation, quality, and safety. The Sequestr External Disconnect Package exemplifies this dedication, offering a reliable and effective solution for managing electrical hazards in demanding industrial environments.
