Type 2 AC surge protector - 3-phase

Part Number 302113
  • Type 2 AC Multipolar surge protector
  • In : 15 kA
  • Imax total : 120 kA
  • Remote signaling for each pole
  • NF EN 61643-11, IEC 61643-11 compliance

Used mainly for wind turbines 3- phase networks at the generator and convertor. This type composed of 3-pole DU30S-1000/WD associated with dedicated surge protector DU100G-3500/WD, this module based on gas tube technology to realize protcetion for harmonic interference which mainly appeared in wind turbines. This surge protectors are designed to be used in a multipolar configuration to protect 3-phase AC networks.
