30 mm Steel Push Button Enclosure

The Wiegmann WPBA2 is a steel enclosure designed to house two 30 mm push buttons in industrial control panels. It carries NEMA 12 and 13 ratings for protection against dust, dirt, and non-corrosive liquids. The sloping front design allows comfortable operator access while the captive cover screws and oil-resistant gasket maintain a secure seal during routine maintenance.

Suited for two-button stations, not larger layouts

This enclosure suits builders assembling compact start-stop or jog-run stations where only two 30 mm operators are required. The single-column layout and external mounting feet simplify installation on flat panel surfaces. Projects needing three or more buttons, a different hole pattern, or integrated conduit entries should select an alternative enclosure style.

Two 30 mm holes on a sloping front

The defining specification is the pair of 30 mm cut-outs arranged in a single column on a sloping front face measuring 3.50 in high by 5.50 in wide. This fixed hole count and orientation determine whether the enclosure matches the intended control station layout.

Questions about this item

How do I mount the Wiegmann WPBA2 enclosure using the external feet, and what step is often missed?

Fasten the four external mounting feet to a flat surface with bolts; the step often missed is torquing the captive cover screws evenly to compress the closed-cell oil-resistant gasket for a proper NEMA 12/13 seal.

What maintenance will the enclosure gasket and grounding stud need over time?

Inspect the closed-cell oil-resistant gasket for cracks or compression set during routine checks and replace if damaged; verify the grounding stud remains tight and free of corrosion to maintain continuity.

At what point does the 30 mm hole spacing limit the number of operators I can fit?

With only two 30 mm holes on a single column across the 5.5 in width, the physical spacing caps you at two operators; adding more requires a larger enclosure.
