Integra Premium series polycarbonate enclosures include a lift-off screw cover, hinged screw cover and single-door hinged cover. The series features a T-rail mounting system for dead-front panels, swing-out panels, layering subpanels and infinitely variable subpanel height. The enclosures weigh less than comparable steel or fiberglass enclosures and are engineered for durability, impact resistance, UV stability and chemical resistance. They have an operating temperature range of -40 to 265 °F. Covers are available in clear or opaque. The enclosures are NEMA-rated, watertight, noncorrosive and nonconductive and are UL-listed and CE-, RoHs- and REACH-compliant.
