Technical informations

T1-12.5M/335-T2 surge arresters offer complete protection for installations, protecting them from both the direct (when a lightning protector is present) and indirect effects of lightning. They are specially designed to be deployed on single-phase or three-phase networks located in areas characterised by extremely high lightning strike density.

Technical specifications :

  • Type 1 and 2 surge protectors
  • Rated/maximum current level: Iimp 12.5 kA / Imax 80 kA
  • Rated discharge current: In 20 kA
  • Integrated thermal disconnection mechanism
