Product details

In a single-phase TT or TN arrester the neutral module carries the spark gap that bridges neutral to earth, and it is a different component from the line module beside it. This DEHN neutral (N) replacement plugs into the existing base part and puts that path back into service.

Key features

  • Neutral (N) replacement module for DEHN combined Type 1 and 2 arresters
  • Restores the N-PE spark gap path used in TT and TN-S configurations
  • Plug-in fit to the installed base part with no re-termination required
  • Replaces only the affected pole, leaving healthy line modules in place
  • Worth stocking on electrode-earthed sites with origin-position protection

Typical applications

Single-phase TT installations with Type 1 protection are typically rural properties, pumping and telemetry stations, masts and outbuildings fed from an overhead supply. The neutral module on these arresters takes the full partial lightning current from the N-PE path, so having the correct spare available keeps a site protected without a second visit.

Compliance

Combined Type 1 and Type 2 devices are classified under the BS EN 61643-11 series. Fit only the neutral module specified for your arrester base - line and neutral modules are not interchangeable.
