Type 1+2 Surge Protective Device N-PE KYSPD-12.5T1+2-1+1 | Kuangya
Type 1+2 surge protective device N–PE for single-phase AC 230 V systems.
Surge ratings: Iimp 12.5 kA (10/350 µs), In 20 kA (8/20 µs), Up ≤ 1.5–2.0 kV.
1+1 topology with MOV (L–N) and GDT (N–PE), pluggable module, optional RC contacts.
specially designed for single-phase 230 V AC TN and TT systems.
It provides coordinated lightning current and surge protection using a 1+1 topology:
MOV between L–N and a gas discharge tube (GDT) between N–PE.This design ensures robust discharge of direct lightning currents (10/350 μs)
while limiting switching surges (8/20 μs), offering comprehensive protection
for residential, commercial, and industrial distribution boards. Its pluggable
module design enables simple replacement, while integrated thermal disconnector
and visual status indication enhance safety. Optional RC signaling contacts
are available for remote monitoring.
