The Type 3 Electrical Cabinet is a step up from the Type 1 or Type 2. Although the Type 2 allows some protection from water, it does not provide enough for it to be classed as an outdoor electrical cabinet. The Type 3 electrical cabinet is an indoor/outdoor electrical cabinet that offers the same basic level of protection as the Type 1 or Type 2 (Keeps personnel from coming into contact with components), but also protects from dust, wind blown dust, rain sleet and snow.
The Type 3 electrical cabinet has a rubber gasket that seals the cabinet, protecting it’s components from more environmental elements. Like all the rated electrical cabinets, they can be built to specific sizes and detentions. A custom metal fabrication company can build you Type 3 electrical to your exact needs and provide many options of components and finishes.
The Type 3R is the same electrical cabinet, but has louvers for ventilation.
