Overview

The nVent Sequestr External Disconnect Package (SKU: A72XD3418FTCLP) is a critical safety solution designed to mitigate arc flash hazards in industrial electrical systems. This pre-engineered package integrates a disconnect switch and fuse block/circuit breaker within a rugged Type 12 enclosure, ensuring compliance with stringent safety standards while simplifying installation for new projects. By isolating incoming power from the main enclosure, it provides technicians with a controlled environment to service interior components without exposure to live circuits, significantly reducing the risk of arc flash incidents—a leading cause of workplace injuries in electrical maintenance operations. Engineered for durability and performance, the Sequestr External Disconnect Package features a gray steel enclosure measuring 72.12" x 34.25" x 18.12", providing robust protection against environmental contaminants such as dust, dirt, and water ingress. The external mounting of the disconnect switch and overcurrent protection components allows for quick access and maintenance, while the internal terminal connections safely route power to the main enclosure. This design is particularly valuable in applications where frequent equipment servicing is required, such as manufacturing plants, data centers, healthcare facilities, and commercial buildings where operational continuity is paramount. The Sequestr package is ideal for facilities that prioritize safety and regulatory compliance, including those adhering to OSHA, NFPA 70E, and NEC guidelines. Its Type 12 rating ensures suitability for indoor use in harsh or industrial environments, where exposure to moisture, non-corrosive liquids, or airborne particulates is common. Professionals in industries such as food and beverage processing, pharmaceutical manufacturing, and automotive production rely on nVent’s solutions to maintain safe working conditions while minimizing downtime during maintenance cycles. Installation is streamlined thanks to the pre-assembled design, shipped as a single unit ready for integration into new electrical systems. This reduces on-site labor costs and potential errors associated with field assembly, while the high-quality steel construction ensures long-term reliability even in high-vibration or high-impact settings. nVent, a global leader in electrical solutions, brings decades of expertise in thermal management, connectivity, and safety systems to this product line, offering customers peace of mind through proven performance and adherence to international standards. Key benefits of the Sequestr External Disconnect Package include: - Enhanced arc flash safety for maintenance personnel - Simplified installation and reduced labor costs - Compliance with Type 12 enclosure requirements for indoor industrial use - Durable steel construction for harsh environments - Pre-engineered design for new installations, minimizing field assembly errors Whether upgrading an existing facility or designing a new electrical system, the nVent Sequestr External Disconnect Package delivers a balance of safety, efficiency, and reliability.
