Transient Discriminating Surge Diverter, 20 kA Three Mode


  • 20 kA 8/20 μs surge rating provides robust surge protection
  • TD Technology with thermal disconnect protection
  • Compact package, modular DIN rail mounting for limited space requirements
  • Three modes of protection: L-N, L-PE and N-PE
  • Indication flags and voltage-free contacts provide remote status monitoring
  • Separate plug and base design facilitates replacement of a failed surge module
