Type 2 surge arrester for lowvoltage power supply system protection against surges at the boundaries from lightning protection zone 1-2 and higher.
Ø Pluggable design, class II 40kA SPD, KEMA certified per IEC61643-11
Ø High reliability due to global patented thermally protected MOV with special arc-extinguish device
Ø VTD technology surge protector, the best technology for power protection
Ø Very low clamping level and high surge current capability (high Iimp, low Up)
Ø High TOV withstand, increased reliability for areas with unstable power network
Ø No follow current, No leakage current, intelligent distinguish power frequency current and surge current to guarantee long service life
