CRITEC TDX - Modular TDX Replaceable Modules TDX Replaceable Module Backplane fully removed Typical Installation

The CRITEC® brand of TDX Modular Series Transient Voltage Surge Suppressors from ERICO® is designed for critical protection applications. The 100kA or 200kA 8/20µSec of surge protection (depending on model) exceeds 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. A flush mounting kit is also available for installing the SPD in drywall applications. Features • Includes CRITEC® Transient Discriminating (TD) Technology, providing increased service life • Modular design allows individual modes to be field replaceable; built-in disconnect and fusing eliminates need for external fusing • Built-in safety features include TD Technology, thermal protection and short circuit current cartridge fusing • Compact NEMA®-4 enclosure design can be flush mounted or installed in a small space • Status indication flag per mode, voltage presence LEDs, audible alarm and voltage-free contacts provide remote status monitoring • 100kA 8/20µSec or 200kA 8/20µSec maximum surge rating (depending on model) provides protection suitable for smaller main distribution panels and an extended operational life • Available in various operating voltages to suit most common power distribution systems • CE, UL® pending Applications • Designed for critical protection applications • Ideal for retrofit to indoor or outdoor service panels More Information Part No. Description TDX100M120/240 TDX100M, 2Ph, 120/240V, 3W+G, 100kA/Phase TDX100M120/208 TDX100M, 3Ph, 120/208V, 4W+G, 100kA/Phase TDX100M277/480 TDX100M, 3Ph, 277/480V, 4W+G, 100kA/Phase TDX100M277/480TT TDX100M, 3Ph, 277/480V, 4W+G, 100kA/Phase, TT system TDX100M347/600 TDX100M, 3Ph, 347/600V, 4W+G, 100kA/Phase TDX100M120/240D TDX100M, 3Ph HI LG, 120/240V, 4W+G, 100kA/Phase TDX100M240D TDX100M, 3Ph DELTA, 240V, 3W+G, 100kA/Phase TDX100M480D TDX100M, 3Ph DELTA, 480V, 3W+G, 100kA/Phase TDX200M120/240 TDX200M, 2Ph, 120/240V, 3W+G, 200kA/Phase TDX200M120/208 TDX200M, 3Ph, 120/208V, 4W+G, 200kA/Phase TDX200M277/480 TDX200M, 3Ph, 277/480V, 4W+G, 200kA/Phase TDX200M277/480TT TDX200M, 3Ph, 277/480V, 4W+G, 200kA/Phase, TT System TDX200M347/600 TDX200M, 3Ph, 347/600V, 4W+G, 200kA/Phase TDX200M120/240D TDX200M, 3Ph HI LG, 120/240V, 4W+G, 200kA/Phase TDX200M240D TDX200M, 3Ph DELTA, 240V, 3W+G, 200kA/Phase TDX200M480D TDX200M, 3Ph DELTA, 480V, 3W+G, 200kA/Phase
