Overview

The nVent Sequestr External Disconnect Package (SKU: A72XD3EQ18SSFTCLP) is a robust Type 4X stainless steel enclosure designed to enhance electrical safety and operational efficiency in industrial environments. Engineered for arc flash mitigation, this 3-door package isolates incoming power from the main enclosure, ensuring technicians can safely service interior components without exposure to live circuits. The enclosure measures 72 inches in height, 100 inches in width, and 18 inches in depth, providing ample space for disconnect switches, fuse blocks, or circuit breakers. Constructed from high-grade 304 stainless steel, the Sequestr External Disconnect Enclosure delivers superior corrosion resistance against non-corrosive or mildly corrosive elements, making it ideal for both indoor and outdoor applications across diverse industries. Arc flash hazards remain a critical concern in electrical installations, particularly in facilities with high-power distribution systems. The Sequestr External Disconnect Package addresses this challenge by physically separating the power source from the main enclosure, allowing maintenance personnel to de-energize equipment before accessing internal components. This external disconnect strategy not only reduces the risk of arc flash incidents but also minimizes downtime by enabling faster, safer inspections and repairs. The enclosure’s Type 4X rating ensures protection against water ingress, dust, and corrosive atmospheres, meeting stringent NEMA and IP standards for harsh environments. Designed for versatility, the Sequestr External Disconnect Package includes a main enclosure paired with a Sequestr box, which can also be purchased separately for retrofitting existing installations. The disconnect switch and fuse block or circuit breaker are pre-mounted in the external enclosure, with terminal connections routed to the main enclosure for seamless integration. This modular approach simplifies installation and future upgrades, reducing labor costs and project timelines. The brushed stainless steel finish not only enhances durability but also provides a professional appearance suitable for cleanroom, food processing, pharmaceutical, and other controlled-environment applications. Industries that benefit from the Sequestr External Disconnect Package include manufacturing plants, data centers, water treatment facilities, chemical processing, and renewable energy installations. In manufacturing, these enclosures protect critical control panels from environmental contaminants while enabling safe maintenance. Data centers rely on them to isolate power distribution units, ensuring uninterrupted operation during servicing. Water treatment plants and chemical facilities leverage the corrosion-resistant properties of 304 stainless steel to withstand exposure to moisture and chemicals. Renewable energy projects, such as solar and wind farms, use these enclosures to safeguard sensitive electrical components in outdoor or coastal environments. Professionals selecting an external disconnect enclosure must consider factors such as environmental conditions, electrical load requirements, and compliance with local codes. The Sequestr External Disconnect Package meets or exceeds UL, CSA, and IEC standards, providing peace of mind for engineers and facility managers. Its modular design allows for customization with various disconnect switches, circuit breakers, or fuse blocks, ensuring compatibility with existing systems. Installation is streamlined thanks to pre-drilled mounting holes and clear labeling, reducing the risk of errors during setup. nVent, a global leader in electrical and thermal management solutions, has built a reputation for innovation and reliability in the industrial sector. With decades of experience, nVent’s Sequestr line of enclosures is trusted by professionals worldwide for its durability, safety features, and ease of use. The company’s commitment to quality is evident in every aspect of the Sequestr External Disconnect Package, from the corrosion-resistant stainless steel construction to the precision-engineered components. For facilities prioritizing safety, efficiency, and long-term performance, the nVent Sequestr External Disconnect Package (A72XD3EQ18SSFTCLP) is an indispensable solution.
