Type 2 AC surge protector - 2-pole - pluggable

Part Number: 462921
  • Type 2 AC surge protector
  • In: 20 kA
  • Imax total: 40 kA
  • Pluggable module for each phase
  • Remote signaling
  • NF EN 61643-11, IEC 61643-11 compliance

Used mainly for wind turbines of 4- phase networks at the converter and generator. This SPD is based on high energy varistor equipped with thermal disconnector and failure indicator, to comply with standards. The DS40 surge protectors are designed to be used in a multipolar configuration to protect 3-phase or 3-phase+Neutral AC networks.
