카테고리:
KYSPD-12.5T1+2-3+1 is a three-phase 전기 패널용 서지 보호 장치
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.
