Southwire SDN (Small Diameter Neoprene) flexible control tray cables 600 Volt are suited for use in industrial power or control circuits where small diameter, flame retardant cables are desired. These cables are suitable for use in wet and dry areas, conduits, ducts, troughs, trays, direct burial and where superior electrical properties are desired. Southwire SDN cables listed as THHN/THWN are capable of operating continuously at the conductor temperature not in excess of 75°C in wet locations and 90°C in dry locations, 130°C for emergency overload, and 150°C for short circuit conditions. For uses in Class I, II, Division 2 hazardous locations per NEC Article 501 and 502. Southwire SDN flexible control cable is CSA listed Type TC and as Control and Instrumentation Cable Type (CIC)
