Max. continuous operating voltage Uc: AC 1000 V 50/60 Hz
Nominal discharge current In (8/20 μs) : 20 kA
Max. discharge current Imax (8/20 μs): 40 kA
Voltage protection level Up: ≤ 4.0 kV, ≤ 4.5 kV
Application:
This surge protective device (SPD) offers robust performance in diverse grid conditions and is specifically designed for application within new energy systems, including wind power, photovoltaic installations, and EV charging infrastructure. It is engineered for installation at key internal nodes such as converters, inverters, combiner boxes, grid-connection cabinets, and charging piles (typically within LPZ1 to LPZ2 zones). Its purpose is to protect sensitive electrical equipment from damage caused by induced transient overvoltages and switching surges.
Featured:
*Nominal discharge current In (8/20 us): 20 kA
