FLP12,5-275/2S

Project Description

FLP12,5-275/2S


Description

Modular surge arrester for use in single-phase TN systems; with floating remote signaling contact.

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