Wiegmann B-CH 10x8x4 Enclosure

The Wiegmann B-CH enclosure provides NEMA 12 and 13 rated protection for electrical components in industrial settings. Its carbon steel body with ANSI 61 gray powder coating resists corrosion and incidental contact. The unit measures 10 inches high by 8 inches wide with a 4 inch depth. It arrives new and carries CSA, cULus and UL certifications.

Hinged Solid Cover With Clamp Closure

A hinged solid cover secures with screwdown clamps and screws to maintain the seal. External mounting plates allow direct wall attachment without additional brackets. A seamless polyurethane gasket is poured in place to block dust and water ingress. The usable opening depth is 3.88 inches for internal hardware such as the 3A928 interior panel.

14/16 Gauge Steel For Continuous Duty

The 14/16 gauge steel construction withstands sustained mechanical stress and thermal cycling in fixed installations. Powder coat finish maintains appearance and protection during long-term exposure to humidity and contaminants. This enclosure is not suited for applications requiring transparent covers or larger internal volumes beyond the stated dimensions.

Questions about this item

How does the 14/16 ga carbon-steel wall thickness limit heat dissipation during continuous operation?

The 14/16 gauge steel and seamless polyurethane gasket seal the enclosure to NEMA 12/13, so internal heat must be managed by the installed components and any added ventilation; the box itself provides no active cooling.

What noise or thermal load does the enclosure add when mounted and powered all day?

The enclosure is a passive steel cabinet with screw-down clamps and poured gasket; it generates no noise or heat of its own, but it traps the heat and sound of whatever devices are installed inside.

Which interior panel and mounting hardware must I already have to use this B-CH series box?

The usable opening depth is 3.88 in and the specified interior panel is 3A928; you must supply that panel plus any DIN rails, bus plugs or breakers that fit within the 10 × 8 × 4 in interior.
