ESP D/BX Series

The ESP D/BX Series is a combined Category D, C, B tested protector (to BS EN 61643) based on the ESP D Series and ESP TN but ready-boxed to IP66 for use in damp or dirty environments. Suitable for most twisted pair signalling applications.

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
  • Ready-boxed to IP66 and supplied ready for flat mounting
  • Available with screw terminals or with IDC terminals (by adding /I suffix to part number)
  • Colour coded terminals for 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
  • ESP TN/BX and ESP TN/2BX are suitable for telecommunication applications in accordance with Telcordia and ANSI Standards (see Application Note AN005)
  • Supplied as standard with screw terminals - for IDC terminals order part code plus /I (e.g. ESP TN/BX/I)
  • ESP TN/BX has Network Rail Approval PA05/02877. NRS PADS reference 087/037286
