E3PBAM

Overview

The Hoffman E3PBAM is a steel pushbutton enclosure with a sloped front design, intended for applications requiring slanted control surfaces. It features a hinged cover and provides mounting space for three outlets compatible with 22.5 mm or 30.5 mm pushbuttons and switches. The unit measures approximately 7-3/4 inches in width, 3-1/2 inches in height, and 4-84 inches in depth. It carries a NEMA 12/IP65 rating to protect against dust, dripping water, and oil non-corrosive coolant. The construction includes continuously welded and ground smooth seams, with captivated cover screws threading into sealed wells.

Feature Summary

• Sloped front design facilitates operation on angled control surfaces
• NEMA 12 and IP65 rated protection against environmental contaminants
• Steel construction with continuously welded and ground smooth seams
• Hinged cover with captivated screws and grounding provisions

Applications

• Industrial control panels requiring slanted operator interfaces
• Environments necessitating protection from dust and non-corrosive coolants
• Mounting 22.5 mm or 30.5 mm pushbuttons and switches
• Control stations where ergonomic access to controls is prioritized

Procurement Notes

Verify the specific voltage and current ratings of the installed pushbuttons and switches, as the enclosure itself does not define these values. Confirm that the NEMA 12 rating aligns with the specific industrial environment's exposure to oils and coolants. Ensure the mounting surface accommodates the external dimensions and that the hinged cover has sufficient clearance for opening. Check for any required accessories such as internal DIN rails or terminal blocks if not included.

Selection Notes

Select this model when a sloped interface is mechanically necessary for operator accessibility. Compare against flat-front alternatives if space constraints differ. Verify compatibility with existing switch standards (22.5 mm vs 30.5 mm). Consider the material finish and grounding requirements relative to other components in the assembly. Evaluate whether the NEMA 12 rating is sufficient or if a higher ingress protection level is needed.

Part Context

This component belongs to the Hoffman E Series of pushbutton enclosures. These units are designed to house manual control devices in industrial settings. The series emphasizes durability through welded steel construction and environmental sealing. It serves as a protective housing rather than an active electronic component, focusing on mechanical integration and operator safety within larger control systems.

Replacement Considerations

Direct substitutes may include other Hoffman E Series models with similar dimensions but different hole configurations. Cross-reference with nVent Hoffman catalogs for updated part numbers. Ensure replacement units maintain the same NEMA rating and slope angle. Verify that mounting hole patterns and depth specifications match the existing panel cutouts.
