AXD20

Overview

The Hoffman Enclosures, Inc. AXD20 is a 20-inch deep external disconnect enclosure constructed from powder-coated steel with a UL Type 12 rating. It features a concealed hinged cover and an interlock mechanism that secures the main control cabinet doors when the disconnect switch is powered on. The unit includes a conductive back panel and provisions for pass-through power into the main cabinet, facilitating retrofit applications to isolate incoming power.

Feature Summary

• Interlocks main control cabinet doors when the disconnect switch is energized
• Includes a conductive back panel for safety grounding
• Provides provisions for pass-through power into the main cabinet

Applications

• Arc flash safety mitigation
• Controls and drives isolation
• Power distribution retrofitting

Procurement Notes

Verify that the specific AXD20 variant matches the required UL Type 12 rating and dimensional constraints of the existing installation. Confirm compatibility with the intended disconnect switch model and ensure the interlock mechanism aligns with the main cabinet door configuration. Review official documentation for any specific mounting hardware requirements or pass-through power specifications.

Selection Notes

Select this enclosure for retrofitting existing setups to enhance arc flash safety by isolating incoming power. Ensure the 20-inch depth accommodates the disconnect switch and wiring space. Verify that the UL Type 12 rating meets environmental protection needs and that the interlock functionality integrates correctly with the associated control cabinet.

Part Context

This component belongs to the nVent Hoffman SEQUESTER series of external disconnect enclosures. These units are designed to be retrofitted to existing installations, allowing operators to move the disconnect switch away from the main control cabinet. This separation helps mitigate arc flash risks by isolating the high-energy switching point from the operator's immediate workspace.
