Surge protection device for electrical panel KYSPD-12.5T1+T2-3P+1 | Kuangya
Three-phase 전기 패널용 서지 보호 장치 in 3+1 topology (L-N + N-PE) for TT / TN-S networks at 230/400 V AC.
Surge ratings (L-N / N-PE): Iimp 12.5 kA / 50 kA (10/350 µs), In 20 kA / 50 kA (8/20 µs), Imax 50 kA / 100 kA (8/20 µs); typical Up options from 1.0/1.5 kV up to 2.0/1.5 kV by variant.
Pluggable modules, thermal disconnector with green/red status, optional RC remote contacts; IP20 housing, UL94-V0 thermoplastic, 35 mm DIN-rail mount.
using a 3+1 topology (L–N + N–PE) for TT and TN-S systems at 230/400 V AC. It combines Type 1
lightning current handling on the N–PE path with Type 2 surge discharge on each L–N path to
protect downstream equipment in main distribution boards.This 전기 패널용 서지 보호 장치 features pluggable cartridges with
thermal disconnection and a clear green/red status window. Optional RC remote contacts enable
fault signaling to BMS/PLC. The compact DIN-rail form factor simplifies integration into
electrical panels for industrial, commercial, and large residential sites.
