Two-hole carbon-steel push-button enclosure

The Wiegmann PB2 is a carbon-steel enclosure with two 30 mm holes in a single column. It is built for industrial electrical controls and automation where operators need a compact, oil-tight station for push buttons or selector switches. The gray finish and NEMA 12, 13 and 4 ratings suit indoor and outdoor environments that see dust, dripping water or oil.

Captive screws and oil-resistant gasket

Captive cover screws stay with the lid so they cannot be lost during maintenance. A closed-cell oil-resistant gasket seals the enclosure against cutting fluids and coolants. External mounting plates let installers fasten the box to a panel or machine frame without opening the cover, preserving the seal.

No conduit entries and fixed hole pattern

The enclosure ships with no conduit entrance holes, so cable glands or fittings must be drilled on site to match the wiring plan. Only two 30 mm operator holes are provided in a single column, limiting the station to two devices. Builders who need more operators, a different hole spacing or pre-punched conduit entries will need a different enclosure.

Questions about this item

Will the captive cover screws or the closed-cell oil-resistant gasket need periodic replacement on the PB2 enclosure?

The captive cover screws are fixed to the cover and do not require replacement; the closed-cell oil-resistant gasket is designed for the enclosure's service life and is not a scheduled maintenance item.

What is the first rating limit reached during continuous exposure to oil or coolant on the carbon-steel PB2 enclosure?

The NEMA 12 and 13 ratings define the oil-tight and coolant-tight limits; sustained immersion beyond those conditions would exceed the enclosure's certified protection.

How much heat can the 5.75 in by 3.25 in by 2.81 in carbon-steel body dissipate when the PB2 enclosure runs all day?

The carbon-steel construction and 5.75 in height by 3.25 in width by 2.81 in depth provide passive heat dissipation; no active cooling or power-dissipation rating is specified for the enclosure itself.
