SLP40-75/1S+1

Project Description

SLP40-75/1S+1


Description

Modular surge arrester for use in single-phase TT and TN systems (“1+1” circuit); 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 varistors/spark gaps
  • High reliability due to “Thermo Dynamic Control” SPD monitoring device
