AutomationDirect has expanded its line of Hubbell Wiegmann enclosures with additional NEMA 3R and NEMA 12 models. NEMA 3R enclosures, typically used in outdoor applications for wiring and junction boxes, provide protection against falling rain, sleet, snow, and external ice formation; they protect against dripping water when used indoors. This style of enclosure does not have a gasketed sealing surface; some models have hasps for padlocking. New models include galvanized steel units, and larger sizes with hinge covers.
Most often used for indoor applications of automation control and electronic drives systems, NEMA 12 enclosures are designed to prevent the ingress of dust, water, and oil. Designed with gasketed doors to seal the enclosure’s contents from airborne contaminants and non-pressurized water and oil, NEMA 12 enclosures are available in sizes from small wall mounts to two-door floor mount models.
