Three-hole steel enclosure

The Wiegmann WPBA3 is a steel pushbutton enclosure with three 30 mm holes arranged in a single column. It is built for industrial control panels that need a compact station for operators to start, stop or select machine functions. The sloping front places the buttons at a comfortable angle for standing or seated use. The grey finish suits standard factory colour schemes.

NEMA 12 and 13 rating

A closed-cell oil-resistant gasket and captive cover screws seal the interior against dust, dirt, dripping water and light splashing oil. The cULus listing confirms compliance with North American safety standards for industrial control equipment. External mounting feet allow the box to be bolted directly to a machine frame or panel without opening the sealed compartment. A grounding stud is provided for bonding the metal enclosure.

No conduit entries supplied

The enclosure ships without pre-drilled conduit entrance holes, so the installer must drill or punch openings that match the cable glands or fittings required by the specific wiring plan. This gives flexibility but adds a fabrication step before installation. Buyers who need ready-to-wire knockouts or a larger number of operator stations will need a different enclosure.

Questions about this item

What NEMA ratings does the enclosure carry, and what environments does that cover?

It is rated NEMA 12 and 13, meaning it protects against falling dirt, circulating dust, lint, fibre flyings, and dripping or light splashing of non-corrosive liquids including oils and coolants.

What are the external dimensions and mounting footprint needed to fit this enclosure?

The enclosure measures 3.50 in high, 7.75 in wide and 4.78 in deep, and it mounts via external feet that extend beyond the body — allow clearance for those feet when planning the panel cut-out.

How is the cover secured, and what step is often missed during installation?

Captive cover screws hold the sloping front closed; the step installers sometimes skip is tightening the grounding stud to the panel to maintain the NEMA 12/13 seal and electrical continuity.
