ESP D & TN Series

The ESP D & TN Series is a combined Category D, C, B tested protector (to BS EN 61643) suitable for most twisted pair signalling applications such as those found in process control equipment, modems and computer communication interfaces.

Available for working voltages of up to 6, 15, 30, 50 and 110 Volts. For use at boundaries up to LPZ 0
to protect against flashover (typically the service entrance location) through to LPZ 3 to protect sensitive electronic equipment.

Features & benefits

  • Very low let-through voltage (enhanced protection to IEC/BS EN 62305) between all lines
  • Full Mode design capable of handling partial lightning currents as well as allowing continual operation of protected equipment
  • Repeated protection in lightning intense environments
  • Low in-line resistance minimizes unnecessary reductions in signal strength
  • Strong, flame retardant, ABS housing
  • Supplied ready for flat mounting on base or side
  • Built-in DIN rail foot for simple clip-on mounting to top hat DIN rails
  • Colour coded terminals give a quick and easy installation check - grey for the dirty (line) end and green for the clean end
  • Screen terminal enables easy connection of cable screen to earth
  • Substantial earth stud to enable effective earthing
  • Integral earthing plate for enhanced connection to earth via a CME kit
  • ESP 06D and ESP 50D have PADS reference 086/000551 (ESP 06D) and 086/000553 (ESP 50D)
  • ESP TN is suitable for telecommunication applications in accordance with Telcordia and ANSI Standards (see Application Note AN005)
