It is approved for UL 508A and CSA standards, suitable for both indoor and outdoor applications.

Feature Summary

• Constructed from heavy-gauge steel frames for durability in industrial environments
• Provides IP66 ingress protection and meets NEMA 4, 4X, 12, and Type 3R ratings
• Designed for easy installation via simple rectangular enclosure cut-outs

Applications

• Indoor industrial control panels requiring visual inspection access
• Outdoor electrical enclosures needing weather-resistant viewing ports
• UL 508A and CSA approved equipment assemblies
• Type 4 and 12 enclosure modifications for operator visibility

Procurement Notes

Verify that the target enclosure supports the required rectangular cut-out dimensions of 29x19 inches before procurement. Confirm that the enclosure material and mounting structure can accommodate the heavy-gauge steel frame weight. Ensure the application environment aligns with the specified NEMA 4, 4X, 12, and Type 3R ratings for proper environmental sealing and corrosion resistance performance.

Selection Notes

Select this kit when visual access to internal components is required without compromising enclosure integrity. It is appropriate for applications demanding high ingress protection (IP66) and compliance with UL 508A or CSA standards. Consider the physical space requirements for the 31.50 x 21.50 inch overall footprint during panel layout planning to ensure adequate clearance for installation and maintenance.

Part Context

This component belongs to the Hoffman Enclosures window kit series, designed as accessories for standard metal enclosures. It serves as a replacement or upgrade option for existing units requiring enhanced visibility while maintaining environmental sealing. The product line focuses on providing robust, pre-framed solutions that simplify retrofitting processes for industrial control and distribution applications.

Replacement Considerations

Direct substitutes include other Hoffman steel window kits with similar dimensional profiles, such as the APWK2315NF for smaller openings. Verify compatibility with specific enclosure models like the A30N24ALP or A30NTMA3 series to ensure proper fitment and sealing integrity after installation.
