| High Light | Type2 surge protection device 20kA ，Single phase lightning arrester 2P ，Indoor AC SPD with TUV | ||
This Class II surge protection device complies with IEC 61643-11, designed for 220Vac single-phase AC power systems in LPZ0B and subsequent secondary lightning protection zones, with independent L-N and N-E dual protection circuits. It features 20kA nominal discharge current and 40kA maximum discharge current under 8/20μs waveform, with multiple Uc ratings from 275Vac to 440Vac to fit grid voltage fluctuations worldwide. ≤25ns fast response clamps transient overvoltage with minimum residual voltage ≤1.25kV. Vibration-resistant pluggable modules integrate ultra-low temperature thermal release, paired with green-red degradation indicator and NO/NC passive remote signalling contacts. PA6 V0 flame retardant housing ensures stable indoor operation from -40℃ to +70℃. Widely applied in residential, retail and small factory single-phase sub-distribution boards to suppress induced surges and switching transients for low-voltage loads.
