A31P21

Overview

The Hoffman A31P21 is a steel internal panel designed for low-profile Type 12 disconnect enclosures. It measures 31.88 inches in height and 21.75 inches in width, with a thickness of 0.121 inches. The panel features a white polyester powder paint finish and is constructed from mild steel. It is specifically engineered to fit 31 x 21 inch A26 Low Profile Type 12 1-Door Disconnect Enclosures, providing a standardized surface for component mounting within the enclosure system.

Feature Summary

• Constructed from mild steel with a white polyester powder paint finish for corrosion resistance.
• Designed as an internal panel for low-profile Type 12 disconnect enclosures.
• Provides a standardized mounting surface compatible with specific Hoffman enclosure series.

Applications

• Installation in A26 Low-Profile Type 12 1-Door Disconnect Enclosures
• Internal panel replacement or addition for 31 x 21 inch enclosure configurations
• Component mounting surface preparation within industrial electrical enclosures

Procurement Notes

Verify that the target enclosure matches the A26 Low-Profile Type 12 1-Door Disconnect model. Confirm internal dimensions are exactly 31 x 21 inches to ensure proper fit. Check that the required panel size corresponds to 31.88 x 21.75 inches. Ensure the application environment is compatible with standard steel panels and does not require specialized coatings beyond the provided white polyester finish.

Selection Notes

Select this part only if the existing enclosure is an A26 Low-Profile Type 12 model requiring a 31 x 21 inch internal panel. The material is mild steel; consider alternative materials if specific environmental conditions demand higher corrosion resistance than the standard powder coat provides. Verify that the white finish meets aesthetic or identification requirements for the installation site.

Part Context

This component belongs to the Hoffman A26 series of low-profile disconnect enclosures. It serves as a critical internal accessory rather than a standalone unit. The panel works in conjunction with the main enclosure body to create a ready-to-populate space for electrical components. It is part of a broader ecosystem of Hoffman enclosure accessories designed for industrial control applications.

Replacement Considerations

No direct substitute part numbers are publicly confirmed for this specific Hoffman internal panel. When replacing, ensure the new panel matches the exact dimensions of 31.88 x 21.75 inches and the material specification of mild steel with white polyester coating. Generic panels may not align with the mounting holes or structural constraints of the A26 enclosure frame.
