Wall-mount enclosure for line protection
The Wiegmann BN4-CH carbon-steel enclosure is built to house circuit breakers and bus plugs in industrial and commercial electrical installations. It carries NEMA 12, 13 and 4 ratings plus IP66, so it resists dust, water spray and oil ingress while meeting CSA, cULus, IEC and UL standards. The ANSI 61 gray powder coat provides durable corrosion protection in harsh environments.
Practical limits of the NEMA and IP ratings
The enclosure withstands non-hazardous indoor and outdoor conditions including falling dirt, dripping water, light splashing and oil or coolant seepage. It is not rated for submersion, high-pressure wash-down or hazardous-location atmospheres, so installations requiring NEMA 4X, 6 or explosion-proof classifications must use a different enclosure series.
14/16-gauge steel with screw-down clamps
The 14/16 ga carbon-steel body and neoprene-gasketed cover fasten with screw-down clamps to maintain the rated seal. Buyers who need a lighter-gauge box, a transparent cover or a latch-only closure will find this construction does not match those requirements.
