NEMA 4 Electrical Enclosures
Bison Profab can manufacture NEMA 4 electrical enclosures in sizes ranging from small wall mounts to two-door floor mount models from a variety of metals depending on your specific application. NEMA 4 enclosures are used for the most sensitive of electrical equipment because of their outstanding protection from the elements. NEMA 4 enclosures are often called rain tight enclosures due to their excellent weather resistance.
NEMA 4 boxes provide a watertight protection against splashing water, indoor wash down from a commercial hose as well as ingress protection from dirt, rain, sleet, snow, ice and windblown dust. If your enclosure is to be used in a corrosive environment you will need to upgrade to a NEMA 4X enclosure most likely fabricated from aluminum or 316 stainless steel.
NEMA 4 enclosures are generally gasketed with doors that clamp to provide a maximum seal. They can also be equipped with continuous hinges, mounting feet, and padlock hasps.
