Hoffman A Series NEMA 3R Screw Cover Enclosure, Galvanized Steel

The Hoffman A Series Screw Cover Enclosure is a NEMA 3R rated electrical enclosure built from galvanized steel and finished in a durable polyester powder paint coating in ANSI 61 Gray. This listing covers the full A Series screw cover enclosure family, offered across ten model configurations — A10R104NK, A10R106NK, A12R124NK, A12R126NK, A12R128NK, A18R186NK, A24R2412NK, A24R246NK, A6R64NK, and A8R84NK — giving specifiers a range of footprint and depth options built to the same construction standard. Each enclosure is engineered to house electrical components, terminations, and control devices in outdoor and industrial environments where protection from rain, sleet, and external ice formation is required. The screw cover design provides a secure, gasketed closure while the galvanized steel construction delivers long-term corrosion resistance for demanding field installations.

Hoffman A6R64NK – Frequently Asked Questions

1) Can a Hoffman A Series screw cover enclosure be mounted outdoors?
Yes. The Hoffman A Series screw cover enclosures carry a NEMA 3R rating, which covers outdoor use with protection against rain, sleet and external ice formation. Body is galvanized steel finished in ANSI 61 Gray polyester powder paint. NEMA 3R is not a washdown or dust-tight rating, so for hose-directed water or oil you need a NEMA 4 or 4X enclosure instead.
2) Are the A Series NEMA 3R enclosures supplied with knockouts, or do I drill my own conduit holes?
No conduit openings are provided. The NK designation on every model (A6R64NK through A24R2412NK) means no knockouts, so you punch the entries where your conduit runs land. On a NEMA 3R box, keep penetrations on the bottom or use raintight fittings on any top or side entry to preserve the rating.
3) How deep an enclosure do I need to fit a small control circuit with a contactor and terminal blocks?
Depth is the thing to check first on the A Series. The shallow 4 inch boxes (6x6x4 through 12x12x4) suit terminations and junction work. Once you are stacking a DIN rail with a contactor and wireway above it, step to a 6 inch depth such as the 12x12x6 or 18x18x6, and for layered control gear or a larger panel use the 24x24x12. All ten share the same galvanized steel screw cover construction, so you are only trading footprint and depth.
4) Is a screw cover enclosure the right choice, or should I use a hinged door box?
A screw cover box like the A Series is made for compartments you open rarely: terminations, splices, wiring junctions, fixed control devices. The cover screws down against a gasket for a weather-resistant seal, which means you need both hands and a driver every time you get in. If the panel will be accessed routinely for resetting breakers or adjusting controls, a hinged-cover enclosure is the better pick.
5) Will the Hoffman A Series galvanized steel enclosure hold up in a coastal or chemical environment?
Galvanized steel with ANSI 61 Gray polyester powder paint gives solid corrosion resistance for general outdoor and industrial exposure. In salt spray, chemical mist or frequent washdown, painted steel is not the right material: specify stainless steel or non-metallic for those openings.
6) Do these Hoffman A Series boxes come with a back panel or mounting hardware inside?
The A Series screw cover enclosures are sold as the enclosure body and cover. Interior space is intended for mounting electrical components, terminations and control devices, and Hoffman's A Series accessories mount in a consistent way across the family, so order the back panel, DIN rail or kit you need as separate line items.
7) Can I standardize a whole site on one enclosure type and still get different sizes?
That is what the A Series platform is for. All ten models share galvanized steel construction, the NEMA 3R rating, the screw cover closure and the ANSI 61 Gray finish, so boxes from 6 x 6 x 4 up to 24 x 24 x 12 look and install the same across a facility. One finish spec and one accessory approach covers every opening.
