ESP H Series

Combined Category D, C, B tested protector (to BS EN 61643), the ESP H Series is suitable for twisted pair signalling applications which require either a lower in-line resistance or an increased current than the ESP D or E Series.

Also suitable for DC power applications less than 4 Amps. Available for working voltages of up to 6, 15, 30, 50, 110 and 180 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
  • Ultra-low (< 0.05 Ω) in-line resistance allows resistance critical applications (e.g. alarm loops) to be protected
  • Very high (4 A) maximum running current
  • 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 clean
  • Screen terminal enables easy connection of cable screen to earth
  • Substantial earth stud to enable effective earthing
  • Integral earth plate enables enhanced connection to earth via CME kit
