OVERVIEW

Application

EPI NEMA Type 4 Aluminum 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.

Construction

These enclosures are made from .125 5052H Quarter Hard Aluminum sheets. 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 a ached with 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.
