NEMA Type 4 Freestanding Enclosure



EPI NEMA Type 4 Freestanding Enclosures are designed to house electrical controls, terminals, and instruments in areas, which may be regularly hosed down or are otherwise very wet. Suitable for use in dairies, breweries, and similar installations. Various interior panels and relay rack angles are available which can be mounted inside.


Made from 14 and 12-gauge galvanized steel. All seams are continuously welded and there are no holes or knockouts. Clamps are provided on three sides of the door to ensure a watertight seal with neoprene gaskets. The gaskets are attached with an oil-resistant adhesive. All exterior hardware (such as clamps, clamp screws, hinge pins, etc.) is stainless steel. A heavy-gauge continuous stainless steel hinge supports the door. A lip is provided around three sides of the door. This lip increases strength and keeps dirt and liquids from dropping into the enclosure. A hasp and staple are provided for padlocking. Panels and relay rack angles must be ordered separately.


Panels must be ordered separately. Floor stand kits in 6, 12, 18, and 24-inch heights are available for factory installation on all single door NEMA 4 enclosures. Drip shield kits protect the door hardware from dripping water and settling dust.


The standard finish is Sherwin Williams ANSI- 70 light dove gray enamel inside and out. Other finishes are available for specific applications.
