ESP Q & TNQ Series

The ESP Q & TNQ Series is a combined Category D, C, B tested protector (to BS EN 61643) suitable for 4 twisted pair lines. Available for working voltages of up to 6, 15, 30, 50, 110 and 180 Volts. ESP TNQ suitable for Broadband, POTS, dial-up, T1/E1, lease line and *DSL telephone applications.

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
  • Almost twice as space efficient as smallest competitor
  • Standard DIN module (18 mm) depth
  • Removable (plug-in) terminals allow pre-wiring of cable looms, for easier installation
  • Suitable for earthed or isolated screen systems
  • Built-in DIN rail foot for clip-on mounting to top hat or G DIN rails
  • Optional flat mounting on side
  • 2.5 mm² terminals allow for larger cross section wiring, stranded wires terminated with ferrules or fitting two wires into a single terminal
  • Very low resistance to minimizes unwanted signal strength reductions
  • Strong, flame retardant, ABS housing
  • Colour coded terminals (grey for line, green for clean) give a quick and easy installation check
  • Screen terminal enables easy connection of cable screen to earth
  • Simple, yet substantial, connection to earth via DIN rail
  • ESP TNQ is suitable for telecommunication applications in accordance with Telcordia and ANSI Standards (see Application Note AN005)
  • Available with Push Terminal options (/PT) for simple 'spring' connections, to provide fast and reliable cable termination
  • ESP 06Q-180Q, and ESP RTDQ (and /PT variants) have UL497b approval under file E240341 (ESP TNQ not included)
