ESP E Series

The ESP E Series is a combined Category D, C, B tested protector (to BS EN 61643) suitable for twisted pair signalling applications which require either a lower in-line resistance, an increased current or a higher bandwidth than the ESP D Series. Also suitable for DC power applications less than 1.25 Amps.

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
  • Very low (1 Ω) in-line resistance allows resistance critical applications (e.g. alarm loops) to be protected
  • High (1.25 A) maximum running current
  • High bandwidth enables higher frequency (high traffic or bit rate) data communications
  • Screen terminal enables easy connection of cable screen to earth
  • Strong, flame retardant, ABS housing
  • 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 clean
  • Substantial earth stud to enable effective earthing
  • Supplied ready for flat mounting on base or side
  • Integral earthing plate for enhanced connection to earth via CME kit
  • ESP 06E and ESP 15E have Network Rail Approval PA05/02047. NRS PADS reference 086/000201 (ESP 06E) and 086/000200 (ESP 15E)
