All types and classes of our lightning and surge arresters 20KA~200KA(8/20μS) and 15KA~50KA(10/350μS) are tested and pass all the requirements based on their class.

AC Surge Protection Device

  • TRS-A Surge Protection Device

    TRS-A Surge Protection Device

    The TRSA series of surge protection device meet the requirements of the standard IEC61643 for the first-class lightning arrester. When used with the latter-stage voltage-limiting lightning arrester, the two-stage lightning arrester can be installed together. Due to the uniquely sealed design structure, there will be no leakage arc even during operation.
