DSD140 (40kA) – DINLINE Surge Diverter


DSD140 (40kA) - DINLINE Surge Diverter

The DSD140 series of surge diverter are designed to provide economical protection to sub-distribution panel boards in locations classified for devices tested to IEC61643-1 test Class II (or VDE classification C). The convenient plug-in module and separate base design facilitates replacement of a failed surge module without needing to undo installation wiring.

A visual indicator flag provides user-feedback if the internal thermal disconnector operates. The “R” series provides a set of voltage-free contacts for remote signaling that maintenance is required.


  • 40kA 8/20µs maximum surge rating provides protection suitable for sub-distribution panels and a long operational life
  • 35 mm DIN 43 880 profile – matches common circuit breakers
  • Indication flag – provides clear visual indication of life status
  • Remote contacts – provide remote status monitoring
  • Various operating voltages – to suit most common power distribution systems
  • ERICO Surge Products are covered by an extended warranty; see the attached document for more information
