NEMA 3 Enclosures

Custom Nema 3 Enclosure

Nema 3 enclosures are weather resistant, and include a degree of protection from windblown dust and ingress of water in the forms of rain, sleet and snow. A Nema 3 rated electrical enclosure will also remain undamaged from the formation of ice on the enclosure.

Nema 3 enclosures are fabricated to house electrical controls, generator skids, or rotating equipment and protect these electrical components aboard shipdocks, on constructions sites, inside tunnels or in subway systems.

Nema 3 Enclosures Applications: Indoor vs. Outdoor

For indoor applications such as industrial structures or labs the metal structure is generally stored in a dry environment but would be equipped to protect against dripping pipes.

Outdoor applications require that the metal junction box be impervious to a range of weather conditions that include rain, wind, sleet and the formation of ice.

Equivalent Replacement for IP Standards

Nema 3 enclosures can be an equivalent replacement for International Protection Ratings: IP54, IP64
