Overview

Enhance electrical safety and mitigate arc flash hazards with the nVent Sequestr High-Amp External Disconnect Enclosure (SKU: AXD542024SSC). Designed by nVent, a trusted leader in electrical protection solutions, this robust enclosure isolates high-amperage disconnect switches and breakers, significantly reducing exposure to live power during maintenance or operation. Its primary function is to provide a secure, external housing for disconnect mechanisms, ensuring that when the disconnect handle is turned to the OFF position, the load-side cables passing through to the main enclosure are de-energized. This critical safety feature is paramount in industrial environments where arc flash incidents pose a severe risk to personnel and equipment. The Sequestr enclosure boasts a substantial size of 54.00x20.00x24.13 inches, offering ample space for up to 800A cable-operated disconnect switches or breakers, compliant with NEC 430.10(B) guidelines. Constructed from durable Type 304 Stainless Steel with a brushed finish, it provides exceptional corrosion resistance and longevity, making it suitable for demanding industrial applications and environments where harsh conditions are prevalent. The NEMA Type 4X rating ensures superior protection against water and dust ingress, as well as resistance to corrosion, further enhancing its suitability for outdoor or wash-down applications. Installation flexibility is a key advantage of the Sequestr enclosure. It is designed for both free-stand and floor-mount configurations, allowing for seamless integration into existing electrical infrastructure or new installations. This versatility ensures that it can be adapted to various site layouts and operational requirements. The enclosure is specifically engineered to interface with nVent's main enclosures, including bulletins A35S, A28S4, and A21S4, facilitating a cohesive and integrated electrical system. For detailed mounting instructions, hole patterns, and specific configuration options, always refer to the comprehensive installation manual provided by nVent. By isolating high-amperage disconnects externally, the Sequestr enclosure not only safeguards personnel from arc flash but also simplifies lockout/tagout procedures. This proactive approach to electrical safety is essential for maintaining operational continuity and compliance with industry safety standards. Invest in the nVent Sequestr High-Amp External Disconnect Enclosure for unparalleled protection and peace of mind in your critical power distribution systems. Its robust construction, advanced safety features, and flexible installation options make it an indispensable component for any facility prioritizing electrical safety and operational efficiency.

How to Install the Sequestr High Amp External Disconnect Enclosure

This guide provides step-by-step instructions for installing the Sequestr High Amp External Disconnect Enclosure to an existing control enclosure.

Estimated time: 1h

Tools needed:

Screwdriver, Drill, Multimeter, Wire strippers

Supplies needed:

Mounting screws, Gasket, Terminal connectors, Hoffman hole seal

  1. Power Down the System

    Turn off the local disconnect installed in the control enclosure and ensure all power to the enclosure is off. Wear appropriate Personal Protective Equipment (PPE) and test for power using a multimeter.

  2. Mount the Sequestr Enclosure

    Remove the subpanel from the Sequestr enclosure. Drill and deburr a hole for the power line entrance. Install the gasket and raise the Sequestr enclosure to the side of the control enclosure. Secure it using thirteen M6x20mm washer head cap screws.

  3. Install the Circuit Breaker/Disconnect Switch

    Drill mounting holes in the panel for the circuit breaker or disconnect switch. Install the mechanism according to the manufacturer's instructions, then secure the populated panel back into the Sequestr enclosure using the saved hex nuts.

  4. Connect Wiring

    Punch or drill holes in the control enclosure to allow wires to pass through. Connect wiring from the load side of the circuit breaker to the existing wiring in the control enclosure, ensuring to seal around the wires to maintain a Type 1 rating.

  5. Power Up the System

    Remove any protective coverings, ensure the operator handle is in the 'OFF' position, and securely close both the Sequestr and control enclosure doors. Restore power to the enclosure and verify the system operates correctly.
