Small SPD (MS15-320-1S)

PRODUCT DETAILS

Features

  • Combination T1+T2 SPD surge protector with compact design only 36mm for single phase.
  • Non exhausting encapsulated spark gap technology with extremely high surge capacity.
  • 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 failure indicator.
