The Largest Polycarbonate Enclosure

As the battle of boxes continues, one of the main issues continues to be how large can you make the box?

Fibox broke new ground with the introduction of the ARCA – JIC series AR24210, measuring 24 x 24 x 10 inches, and shortly after created the ARCA – IEC 806030.

The IEC (International Electrotechnical Commission) is an international committee that develops and publishes its recommendations for standardizing global wiring devices and products. Ingress Protection (IP) is the grades of protection against external solids contacting the conductors of a wiring device and against the penetration of liquids into the wiring device.

The ARCA – IEC 806030 measures 32 x 24x 12 inches and is without a doubt the most massive non-metallic polycarbonate enclosure in the marketplace.

NEMA 4X Cabinet Enclosure

The genesis of these lines was to raise the bar and offer users of fiberglass and metal boxes and better choice. The result? The largest polycarbonate enclosures on the market. The 24X24X10 ARCA polycarbonate enclosures are customizable to fit your needs.

The ease of making modifications to Fibox polycarbonate enclosures makes it ideally suited for many applications and industries and settings. The Fibox polycarbonate material used in the ARCA lines is known for its high impact and UV resistance. It is also lightweight, cost-efficient, and WIFI friendly. However, the largest advantage Fibox’s polycarbonate enclosures is that it is quick and easy to modify the enclosure, both in our warehouse or in the field.
