TDX100C277/480

TDX100C277/480 is a TDX100 compact series transient discriminating panel protection. This transient voltage surge suppressor designed for critical protection applications. The 100KA 8/20µs of surge protection meets the IEEE® C62.41.2 scenario II single shot surge rating requirements for exposed service entrance locations exposure 3. The NEMA-4 weather-tight housing allows the TDX to be installed on indoor or outdoor service panels. The preconfigured connecting leads simplify installation. The unique narrow construction allows the SPD to fit between adjacent panel boards and connect via a 90-degree elbow. Listed as a type 1 SPD to UL 1449 Edition 4, it can be installed within a type 1 or 2 location in accordance with the NEC® 2017. ANSI®/IEEE® C62.41.2-2002 Cat A, Cat B, Cat C, ANSI®/IEEE® C62.41.2-2002 scenario II, exposure 120KA 8/20μs, 2KA 10/350μs.
