Overview

The nVent Sequestr External Disconnect Package (SKU: A90XD7820FTCLPG) is a Type 12-rated enclosure designed to enhance electrical safety by isolating incoming power from the main enclosure during maintenance or service operations. This external disconnect solution mitigates arc flash risks, protecting personnel and equipment while ensuring compliance with NFPA 70E and OSHA safety standards. Shipped as a pre-assembled unit, the package includes a disconnect switch and fuse block or circuit breaker mounted in the external enclosure, with dedicated terminal connections to safely route power to the main enclosure. This industrial-grade external disconnect package is engineered for environments where electrical safety and operational reliability are critical. The Type 12 enclosure (90.12 x 78.50 x 20.12 mm) provides robust protection against dust, dirt, and non-corrosive liquids, making it ideal for manufacturing plants, data centers, commercial buildings, and utility installations. The gray steel construction ensures durability and corrosion resistance, while the two-door design allows for clear separation of power sources and easy access for maintenance. Professionals select the nVent Sequestr External Disconnect Package for its ability to simplify lockout/tagout (LOTO) procedures, reduce downtime during equipment servicing, and enhance overall electrical safety. The external mounting of the disconnect switch enables technicians to isolate power without entering the main enclosure, significantly lowering the risk of arc flash incidents. This solution is particularly valuable in applications where frequent equipment access is required, such as motor control centers, panelboards, and industrial machinery. Installation is streamlined thanks to the pre-wired terminal connections, which reduce on-site labor and minimize potential wiring errors. The package is designed for new installations, ensuring compatibility with standard electrical infrastructure. nVent’s reputation for engineering high-performance electrical solutions is underscored by this product, which leverages decades of expertise in thermal management, connectivity, and safety solutions. Key applications include: - **Manufacturing facilities** requiring frequent equipment maintenance. - **Data centers** where power reliability and safety are paramount. - **Commercial buildings** with stringent electrical safety regulations. - **Utility installations** needing robust, weather-resistant enclosures. - **Industrial automation** environments where arc flash mitigation is critical. By choosing the nVent Sequestr External Disconnect Package, facility managers and electrical contractors invest in a solution that prioritizes safety, efficiency, and compliance.
