E3PBA

Overview

The Hoffman E3PBA is a sloped-front pushbutton enclosure constructed from 14-gauge steel. It features continuously welded and ground-smooth seams with a polyester powder-coated ANSI 61 gray finish. The unit includes captivated cover screws that thread into sealed wells to enhance environmental protection. Standard dimensions are 3.50 inches in length, 7.75 inches in width, and 4.88 inches in depth. It is designed to accommodate three 30.5 mm or 22.5 mm push buttons and switches.

Feature Summary

• Sloped front design for ergonomic operator access
• Continuous welding with ground smooth seams for structural integrity
• Captivated cover screws engaging sealed wells for improved sealing

Applications

• Industrial control panels requiring push button integration
• Machine tool operator interfaces
• Process automation stations

Procurement Notes

Verify the specific mounting hole configuration and internal volume requirements against your component layout before ordering. Confirm that the 14-gauge steel thickness meets your mechanical load specifications. Ensure the ANSI 61 gray finish aligns with existing panel aesthetics. Check for any required accessories such as gaskets or specific screw types not included in the standard assembly.

Selection Notes

Select this model when a sloped interface is necessary for visibility and reach. The 14-gauge steel provides robust protection for sensitive switching components. Consider the external dimensions carefully to ensure fit within the designated cutout space. Verify compatibility with both 30.5 mm and 22.5 mm device diameters if mixed configurations are planned.

Part Context

This component belongs to the Hoffman E Series of industrial enclosures. These units are engineered for harsh environments where durability and operator accessibility are critical. The series typically offers various sizes and configurations to support different numbers of controls while maintaining consistent material quality and finish standards across the product line.

Replacement Considerations

Alternate part number 8303778 is listed as an equivalent option. Verify dimensional tolerances and mounting hole patterns match exactly to avoid modification during installation. Confirm that the replacement unit maintains the same 14-gauge steel construction and finish specifications.
