A86M4E20

Overview

The nVent Hoffman A86M4E20 is a free-standing, multi-door industrial enclosure constructed from mild steel with a polyester painted finish. It features an ANSI 61 Gray exterior and White interior color scheme. The unit measures approximately 86.12 inches in height, 149.19 inches in width, and 20.12 inches in depth. Designed as a Type 12 enclosure, it provides protection against falling dirt, dripping non-corrosive liquids, and oil or grease sputtering. The construction includes continuously welded and ground smooth seams without holes or knockouts.

Feature Summary

• Four-door configuration with concealed easy-to-remove hinges and a three-point latch system equipped with a padlocking handle.
• Overlapping two-door openings feature gasketed centerposts and mechanical interlocks to enhance security and environmental sealing.
• Heavy steel back stiffeners are integrated to maintain flatness and increase overall structural rigidity.
• Seams are continuously welded and ground smooth, eliminating holes or knockouts for a seamless protective barrier.

Applications

• Industrial control panel assembly environments requiring Type 12 protection ratings
• Facilities exposed to falling dirt, dripping non-corrosive liquids, or oil and grease sputtering
• Large-scale electrical equipment housing where mechanical interlock security is required

Procurement Notes

Verify the specific model suffix when ordering, as variations such as G (Gray) or LP (Less Panel) exist within the same dimensional family. Confirm that the base model A86M4E20 corresponds to the standard four-door configuration with full panels. Ensure compatibility with existing mounting infrastructure given the substantial dimensions of the free-standing unit. Cross-reference official nVent documentation to confirm current manufacturing status and availability before finalizing procurement plans.

Selection Notes

Select this model for applications demanding high-security access through mechanical interlocks and robust physical protection. The Type 12 rating makes it suitable for indoor industrial settings with moderate environmental contaminants. Consider the large footprint and weight due to heavy steel construction during site planning. Verify if pre-drilled panels are required, as some variants may be supplied less panel.

Part Context

This component belongs to the nVent Hoffman Free-Stand Series, designed for heavy-duty industrial use. It represents a standard offering in their mild steel enclosure lineup, emphasizing durability and security. The series typically supports various door configurations and sizes to accommodate diverse control panel needs within factory and utility environments.

Replacement Considerations

Direct substitutes include models like A86M4E20G for identical specifications with confirmed gray finish, or A86M4E20LP if panel-less delivery is acceptable. Verify dimensional equivalence and Type 12 compliance when considering alternative manufacturers.
