Primary Function: Designed to protect electrical systems and sensitive electronic equipment against transient overvoltages and lightning surges in AC power distribution networks.
Wiring Setup: Connected across the three live phases (L1, L2, L3), Neutral (N), and routed to the ground terminal at the bottom to safely shunt high surge currents away from protected loads.
Maintenance: The pluggable modular design allows for easy inspection. If the indicator window turns red (“Red Replace”), the respective cartridge module needs to be swapped out.
Pole Type: 4-Pole (L1, L2, L3, and N connections at the top)
Continuous Operating Voltage (Uc): 385V
Maximum Discharge Current (Imax): 40kA
Nominal Discharge Current (In): 20kA
Voltage Protection Level (Up): Below 2.0kV (<2.0kV)
Status Indicators: Features visual failure indicators on each module (displays Green during normal operation, and shifts to Red when replacement is required).
