The ESP 06E is a combined Category D, C, and B tested protector (to BS EN 61643) suitable for twisted pair signalling applications requiring 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.

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 protection.
  • Full Mode design capable of handling partial lightning currents as well as allowing continual operation of protected equipment.
  • 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 make installation checks quick and easy—grey for the dirty (line) end and green for clean.
  • 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).


Use these units to protect resistance-sensitive, higher-frequency, or running-current systems, such as high-speed digital communications equipment or systems with long signal lines.


Connect in series with the data communication or signal line near where it enters or leaves the building or close to the protected equipment (e.g. within its control panel). Either way, it must be very close to the system’s earth star point. Install protectors either within an existing cabinet/cubicle or in a separate enclosure.
