ARCA – IEC

NEMA Cabinets

Driven by innovation and market demand. The ARCA – IEC is the ideal and cost-effective alternative to stainless steel NEMA cabinets or fiberglass enclosures. Made for harsh and demanding environments, these NEMA 4X cabinets are a real game-changer.  The IEC series is the largest polycarbonate UL listed, NEMA 4 cabinet in the world, sized up to 32 x 24x 12 inches.

ARCA -IEC cabinets are available in both portrait and landscape orientation consequently offering greater versatility. The IEC series offers you the first real enclosing alternative to steel boxes. Thanks in part to its high impact resistance, this watertight, UV resistant polycarbonate enclosure will not dent, rust, crack or bloom like steel or fiberglass, therefore offering greater field life. Polycarbonate cabinets weigh considerably less and are easier to modify than its metal or fiberglass counterparts, saving both time and money.

A Cabinet for today’s market

The ARCA – IEC is manufactured in Fibox’s Wi-Fi friendly polycarbonate, a rust-free, high impact plastic. As a result of the formed-in-place PUR gasket your components stay dry and dust-free. Therefore this watertight seal, protects in the rain, sleet and snow. In conclusion these features are just a few of the reasons why the ARCA – IEC is your ideal NEMA 4 cabinet enclosure solution for any enclosing applications.

Polycarbonate hinged electrical cabinets

For extra security, the ARCA – IEC features internal hinges, and quarter turn DIN locks therefore minimizing tampering.  ARCA cabinets are ideal for protecting electrical wiring and components against various hazards, such as falling dirt, windblown dust, dripping water, and splashing of oil and noncorrosive agents.

Custom enclosures
