A31-1207DTHPL2

Overview

The A31-1207DTHPL2 is an insulated electrical junction box manufactured by Hoffman Enclosures, Inc. It features a fiberglass reinforced polyester (FRP) construction with a light gray finish. The enclosure measures 11.89 inches in length, 7.32 inches in width, and 6.93 inches in height. It is rated for Type 4X environments, providing protection against corrosion, water, and dust ingress suitable for harsh industrial settings.

Feature Summary

• Constructed from fiberglass reinforced polyester for enhanced durability and corrosion resistance
• Includes a transparent inspection window to allow visual monitoring of internal components without opening the door
• Designed specifically as an insulated electrical junction or terminal wiring box

Applications

• Insulated electrical junction boxes
• Terminal wiring boxes
• Harsh industrial environments requiring Type 4X protection

Procurement Notes

Verify the specific model suffix DTHPL2 to ensure the inclusion of the transparent inspection window and the correct fiberglass material composition. Confirm that the Type 4X rating aligns with the environmental requirements of the installation site. Check for compatibility with required mounting hardware and cable entries, which may be sold separately.

Selection Notes

Select this model when insulation and corrosion resistance are critical for the application. The transparent window feature distinguishes it from standard opaque enclosures, facilitating maintenance checks. Ensure the internal volume accommodates the necessary wiring and terminal blocks while maintaining safe clearance distances.

Part Context

This component belongs to the APO series of wall-mount enclosures designed for demanding electrical applications. The series emphasizes robust materials like FRP to withstand corrosive atmospheres where standard steel enclosures might fail. It serves as a protective housing for electrical connections in various industrial sectors.

Replacement Considerations

When replacing existing units, verify dimensional compatibility with existing cutouts and mounting points. Ensure the replacement maintains the same Type 4X rating and material specifications to preserve environmental protection standards.
