Combined type 1 & 2 device – lightning current and surge arresters

  • High performance lightning current arrestor
  • Installation at the boundary of zones LPZ 0 and LPZ 1 or higher, mainly to main distribution boards
  • For protection against impact of direct or indirect lightning strikes in a wide range of applications
  • No follow current, no leakage current
