DSD (DC) Series – DINLINE Surge Diverter


DINLINE Surge Diverter

The DSD120 series is designed to provide protection for higher load current circuits that are exposed to higher transient levels, such as those which exit the facility building. The DSD120 series provides a high series current rating of 10A, making it especially useful on power supply circuits and higher current relay control circuits.


  • Ease of grounding – through DIN mounting rail or via terminal
  • General purpose barrier – protection of 12 / 24V DC systems and equipment
  • Large surge rating to 20kA 8/20µs – suitable for exposed DC wiring
  • Separate plug and base design – facilitates ease of module replacement
  • Two stage protection – suitable for the protection of power supply feeds
  • High series current rating of 10A
  • ERICO Surge Products are covered by an extended warranty; see the attached document for more information
