Based on market demand for affordable alternatives to metal cabinets, ARCA-IEC series has added three new sizes, including ARCA No-MP303021(12 x 12 x 8 in.), ARCA No-MP404021 (16 x 16 x 8 in.), and ARCA No-MP505021 (20 x 20 x 8 in.). They offer the same features as the ARCA-IEC product family, including high impact resistance (IK 10) and an IP 66 ingress protection rating that’s UL listed and rated NEMA 4X. Radio transparent polycarbonate eliminates the need for an external antenna. ARCA-IEC also features UV stabilized polycarbonate.
