ED3PBM

Overview

The Hoffman ED3PBM is a drawn steel pushbutton enclosure with dimensions of 8 inches in length, 4 inches in width, and 3.75 inches in depth. It features three outlets designed for 22.5 mm hole size components. The unit provides NEMA Type 4, Type 12, Type 13, and IP66 protection ratings. Constructed from mild steel with a polyester powder coated finish in ANSI 61 gray, it holds UL 508A, CUL, and CSA C22.2 approvals.

Feature Summary

• Drawn steel construction eliminates welded seams and sharp corners for enhanced safety and durability
• Provides comprehensive environmental protection meeting NEMA Types 4, 12, 13, and IP66 standards
• Designed specifically to accommodate 22.5 mm or 30.5 mm four-way pushbuttons and switches

Applications

• Industrial control panels requiring dust-tight and water-resistant housing
• Outdoor machinery interfaces needing high ingress protection
• Safety switch installations in harsh manufacturing environments

Procurement Notes

Verify that the specific application requires the 22.5 mm hole configuration, as this model is distinct from variants supporting 30.5 mm components. Confirm that NEMA Type 4 compliance meets the environmental demands of the installation site. Ensure mounting hardware is compatible with the drawn steel design. Check for any regional certification requirements beyond UL and CSA if deploying internationally.

Selection Notes

Select this model when three separate operator stations are needed within a compact footprint. Choose over welded alternatives if seam integrity and smooth internal surfaces are critical. Consider the 16-gauge steel thickness for structural rigidity. Evaluate space constraints against the 8x4x3.75 inch external dimensions to ensure fitment within the larger assembly.

Part Context

This component belongs to the Hoffman Drawn Enclosures Series, which specializes in pushbutton housings. Unlike traditional fabricated boxes, these units are formed from single sheets to remove internal welds. This series prioritizes operator safety and ease of cleaning by avoiding crevices where debris might accumulate.

Replacement Considerations

No public confirmed substitute part numbers are available.
