Surge Arrester – Type 1+Type 2

FLP7-275/1S+1+Spare module (OBO)

Modular surge arrester for use in single-phase TT and TN systems (“1+1” circuit); with floating remote signalling contact.

  • Prewired complete unit consisting of a base part and plug-in protection modules
  • High discharge capacity due to heavy duty zinc oxide varistors / spark gaps
  • High reliability due to “Thermo Dynamic Control” SPD monitoring device
