It includes stainless steel screws for secure assembly.

Feature Summary

• Extra-deep construction designed to accommodate 30.5 mm and 22.5 mm pushbuttons and switches
• Hinged cover design facilitates easy access for wiring and maintenance
• Stainless steel hardware ensures durability and corrosion resistance
• High-performance powder paint finish provides environmental protection

Applications

• Industrial control station installations requiring NEMA Type 4 protection
• Wall-mounted operator interface housing for heavy machinery
• Enclosures for environments demanding IP66 ingress protection
• Control panels utilizing standard 30.5 mm pushbutton components

Procurement Notes

Verify the specific application environment against the NEMA Type 4 and IP66 ratings to ensure adequate protection. Confirm that the required pushbuttons match the 30.5 mm hole specification. Check for compliance with UL 508A and CUL standards if applicable to your region. Ensure the mild steel material and gray finish meet aesthetic and corrosion requirements for the installation site.

Selection Notes

Select this model when extra depth is necessary for complex wiring or larger switch mechanisms within a compact footprint. The hinged cover simplifies installation compared to removable doors. Consider the mild steel construction for cost-effective durability where extreme corrosion is not a primary concern. Verify that the 8x4 inch faceplate fits the available panel space.
