  • Product typeBus Plugs
  • NEMA 12, 13 and 4 ratings protect against dust, oil and water ingress
  • ANSI 61 gray powder coat resists corrosion in harsh industrial environments
  • Carbon-steel body with neoprene gasket seals out contaminants reliably

  • Hinged screw-down clamps and external mounting plates speed up wall installation

Wiegmann BN4-CH enclosure

The Wiegmann BN4-CH is a carbon steel enclosure finished in gray ANSI 61 powder coat. It carries NEMA 12, 13 and 4 ratings plus IP66 protection for indoor and outdoor use. The unit is CSA certified, cULus listed and meets IEC and UL standards. It suits electrical installations that require a robust, wall-mountable housing.

Sustained-load behaviour

The 14/16 gauge steel body and neoprene gasket maintain a consistent seal during continuous operation. Hinged cover with screw-down clamps keeps the solid door secured under vibration or thermal cycling. Internal panel 6XC20 provides a stable mounting surface for breakers or terminal blocks over long duty cycles.

Thermals, noise and power

Passive metal construction produces no fan noise and draws no power. Powder-coated surfaces dissipate heat from installed devices without active cooling. The 3.88 in usable opening depth allows adequate airflow around components while maintaining the rated ingress protection.

Questions about this item

Does the 14/16 ga carbon-steel body with NEMA 12/13/4 rating trap heat when mounted in a sunny outdoor cabinet?

The ANSI 61 powder coat reflects some solar gain, but the solid cover and neoprene gasket seal the interior; passive dissipation relies on the 3.88 in usable depth and external mounting plates conducting heat to the structure.

What separate parts are required before the BN4-CH can accept a bus plug?

You need the matching 6XC20 interior panel and the specific bus-plug unit rated for the enclosure's NEMA 12/13/4 and IP66 seals; clamps and gasket are already fitted.

Will the clamps and gasket on this series still seal against a legacy panel drilled to an older Wiegmann bolt pattern?

The BN4-CH uses the current 6XC20 panel layout; if the older panel matches those mounting holes and thickness, the neoprene gasket and screw-down clamps will maintain the NEMA 12/13/4 and IP66 rating.
