Description

About this item

2-pole single-phase secondary surge arrester with high surge capacity, rated 20kA nominal discharge and 40kA maximum discharge under 8/20μs waveform. It withstands frequent daily grid induced surges and short-term heavy overvoltage impacts. Dual independent L-N and N-E diversion circuits with ≤25ns nanosecond response suppress voltage spikes rapidly, residual voltage controlled from 1.25kV to 2.0kV for different Uc models. Plug-in modular design allows single faulty cartridge replacement on site; built-in low-temperature trip prevents accidental disconnection in cold cabinets. Equipped with green-red status window and passive remote contacts, 35mm DIN rail compatible footprint, PA6 V0 flame retardant housing stable from -40℃ to +70℃ indoors. Suitable for household consumer units, retail panels, small solar single-phase inverter cabinets and EV charger auxiliary circuit lightning protection.


Product features
1.Module pluggable and anti vibration design
2.Built-in ultra-low temperature release mechanism
3.Application scenarios:Suitable for installation in LPZ 0B-1 and subsequent lightning protection zones, used as a lightning arrester for single-phase power supply systems.
