AXD18

Overview

The Hoffman Enclosures AXD18 is a Sequestr external disconnect enclosure constructed from 16-gauge steel. It features an 18-inch depth with dimensions of 34.45 inches in height and width. The unit includes continuously welded and ground seams for structural integrity and utilizes a right-side hinge configuration. Designed as a retrofit solution, it isolates incoming power to mitigate arc flash risks while passing power through to the main enclosure.

Feature Summary

• Retrofit design for isolating incoming power to mitigate arc flash occurrences
• Constructed from 16-gauge steel with continuously welded and ground seams
• Hinged on the right side for access

Applications

• Retrofitting existing electrical systems to isolate incoming power
• Mitigating arc flash hazards by relocating disconnect switches
• External disconnect installations requiring Type 12 protection

Procurement Notes

Verify that the specific installation requires the standard steel construction rather than stainless steel variants like the AXD18SS. Confirm that the 18-inch depth and 34.45x34.45 inch footprint align with the available space for the retrofit kit. Ensure the application supports the Type 12 rating if indoor use is intended. Check compatibility with the specific disconnect switch being relocated into the Sequestr enclosure.

Selection Notes

Select this model when a dedicated external disconnect location is needed to separate the utility connection from the main distribution panel. It is suitable for projects prioritizing worker safety through arc flash mitigation. Consider the stainless steel version if the environment requires corrosion resistance beyond standard steel capabilities. Verify that the 16-gauge steel thickness meets local code requirements for the specific load.

Part Context

This component belongs to the nVent Hoffman Sequestr line of external disconnect enclosures. These units are engineered specifically for retrofit applications where moving the disconnect switch away from the main enclosure reduces hazard exposure. The AXD18 represents the standard steel variant with an 18-inch depth, distinct from the stainless steel AXD18SS or other depth options within the series.

Replacement Considerations

The AXD18SS serves as the stainless steel alternative for corrosive environments. Other depths may be required if spatial constraints differ from the 18-inch specification.
