Project Description

SLP40-150/1S


Description

Pluggable single-pole surge arrester consisting of a base part and plug-in protection module; with floating changeover contact.

  • Multi-purpose surge arrester consisting of a base element and plug-in protection module
  • High discharge capacity due to heavy duty zinc oxide varistor
  • High reliability due to “Thermo Dynamic Control” SPD monitoring device
