Type 2/Class C Protection: At DB & UPS of 3 – phase supply

Switching surge arresters Type 2 & Class C according to EN 61643-11 & IEC 61643-1 for the lightning protection zone 1-2 consisting of din mountable - one common base consisting of 3 numbers of modular pluggable units of high energy varistor based technology to be connected between line to neutral and 1 number of GDT tube connected between neutral to earth complying the below technical parameters:

       a) Nominal voltage between L-N, Un = 230volts

       b) Maximum continuous operating voltagebetween L-N, Uc = 320 volts

       c) Maximum continuous operating voltagebetween N-PE, Uc = 255 volts

       d) Lightning Impulse Current (N-PE), Iimp (10/350 micro sec) = 25 KA

       e) Nominal discharge current (L-N), In (8/20 micro sec) = 20 KA

       f) Nominal discharge current (N-PE), In (8/20 micro sec) = 30 KA

       g) Max discharge current Imax (8/20 microsec),(L-N)= 40 KA & (N-PE) = 50 KA

       h) Voltage Protection Level, Up = <1.4 KV (L-N), < 1.2 KV (N-PE)

       i) Response time, tA = < 25 (L-N)&< 100 (N-PE) nano seconds

       j) Working condition of the SPD - Visualindication = Green “OK” & Red “Failure”
