  • Surge arresters type T3 with high-frequency filters for serial connection.
  • Intended for protection of electronic appliances against the effects of switching, induced and residual overvoltage in insulated power supply systems.
  • Contain an improved thermal fuse, which ensures timely disconnection of HSAF* S from the power grid during the MOV‘s overheating and thus prevents damage to the HSAF* S.
  • Installed at the boundaries of LPZ 2 – LPZ 3, as close to the device to be protected as possible (no further than 5 m).
  • In front of HSAF* S must be installed a lightning current and surge arrester T1 and T2 from HAKEL company.
  • S indication specifies a version with remote monitoring.
