Weidmüller Surge arrester VPU LCF

Multipole lightning current arrester according to the requirements of class I according to IEC 61643-11, EN61643-11:2013 the arrester made of V0 material serves as lightning protection equipotential bonding at the transition of interfaces 0 to 1 (according to IEC 1312-1) and is used in applications according to IEC 61643-12. By using a non-blowing spark gap in combination with a high-power varistor, the requirements for the verifiability of class I surge protective devices from the VDEW guideline are met. The arrester is installed near the feeder of the equipment to be protected in a standard installation/distribution box. The VPU I 2 LCF 280V/25kA Is used in the single-phase network. With thermal disconnection device of the varistor. When there is no more protection, the color in the display window changes from green to red.
