Surge arrester KSD-T2 275V 40kA Kanlux

Limiter overvoltage with varistors of class 2 (T2 / C): used to protect LV power supply systems from the effects of induced and connection overvoltages / in buildings without lightning protection systems and with cable connections, the limiter provides sufficient protection without the need for class 1 limiters (T1 / B). 
Overvoltage protections class II, type 2 (group C). Surge arresters (SPD) type KSD-T2, type 2 class II, are manufactured according to EN61643-1. These type 2 surge arresters are designed to protect the low voltage installation from direct and indirect lightning strikes and grid connection surges. The limiters guarantee protection within zone 1-2 in compliance with the EN62305 standard.
