Industrial Control Enclosure

The Hoffman E1PBX is a steel enclosure built to house a single 30.5 mm pushbutton. It is constructed from 16 or 14 gauge steel with a gray finish and carries NEMA 12, cUL and CSA C 22.2 certifications. The box measures 4.00 in high, 4.00 in wide and 4.75 in deep.

Panel Builders and Maintenance Teams

This enclosure suits installers who need a compact, rated housing for one operator device on machinery or control panels. It is not intended for applications requiring multiple pushbuttons, additional conduit entries or a different mounting style.

4.75 in Extra Deep Body

The 4.75 in depth provides the extra internal space needed for deeper contact blocks or wiring behind the single 30 mm hole. If your panel layout demands a shallower box or more than one cutout, this model will not fit the requirement.

Questions about this item

How do I mount the E1PBX enclosure and what is the common mistake?

Fasten the external feet to a flat surface, then secure the cover with the captive screws while ensuring the oil-resistant gasket seats evenly; the step often missed is forgetting to attach the grounding stud before closing the cover.

What maintenance will the gasket and finish require over time?

Inspect the oil-resistant gasket periodically for cracks or compression set and replace it if sealing degrades; the gray steel finish needs only occasional cleaning, but touch up any scratched areas to maintain corrosion resistance.

At what point does heat buildup become the limiting factor during continuous operation?

The NEMA 12 rating and extra-deep 4.75 in depth aid dissipation, but with no ventilation provisions the enclosure will reach its thermal limit first when internal components generate sustained heat beyond what the steel walls can radiate.
