Primary Surge Diverter with Triggered Spark Gap, 200 KA

The CRITEC Transient Discriminating MOVTEC Protection Module (TDS-MPM) integrates three CRITEC TDS-MOVTEC units into one enclosure to simplify three-phase protection applications.The TDS-MPM is ideal for primary point of-entry protection applications where it is connected to the main service panel.


  • Primary protection suitable for high exposure sites and point-of-entry facility protection
  • Modular design allows easy replacement of surge modules
  • Five segment electronic status indication displays percentage of capacity remaining
  • Lug connection allows Kelvin (in and out) connection of large cables
  • Transient Discriminating (TD) Technology provides increased service life
