Type1+Type2+Type3 SPD

PRODUCT DETAILS

Features

  • Small combination T1+T2+T3 SPD surge protector only 72mm for three phases.
  • Spark gap technology with high surge capacity and low voltage protection level.
  • High follow current extinction and limitation due to no follow current.
  • Reliable supervision due to new LTR energy control technology.
  • With remote signaling contact optional and mechanical failure indicator.
