PROTECT surge arresters are designed to protect devices in low-voltage power systems against direct and indirect atmospheric overvoltages and switching overvoltages. They are used primarily on low voltage overhead lines. The limiters meet the requirements of the following standards:
IEC-EN 61643-11 and LVD 2014/35/EU (dated 26.02.2014).
The PROTECT clamp series is dedicated to limiters. These are insulation-piercing line terminals that meet the requirements of the PN-EN 50483-4:2009 standard. Short circuit strength – Class A; double-sided insulation-piercing terminals, water-tight – Class 1.
