KYSPD-12.5T1+2-3+1 is a three-phase 電気盤用サージ防護装置
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 電気盤用サージ防護装置 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.主な特徴
- 3+1 coordinated protection for TT / TN-S networks (L–N MOV, N–PE GDT+MOV).
- Surge capability (L–N / N–PE): Iimp 12.5 kA / 50 kA (10/350 μs); In 20 kA / 50 kA;
Imax 50 kA / 100 kA (8/20 μs). - Voltage protection levels (Up) available from 1.0/1.5 kV up to 2.0/1.5 kV depending on Uc.
- Follow current interrupt rating (N–PE) 100 A RMS; fast response < 25 ns / < 100 ns (L–N / N–PE).
- Pluggable, serviceable modules with green (OK) / red (fault) indicator.
- Optional RC remote contacts; AC 250 V / 0.5 A, DC 250 V / 0.1 A, 125 V / 0.2 A, 75 V / 0.5 A.
- Housing IP20, thermoplastic UL94 V-0; 35 mm DIN rail (EN 60715) mounting.
- Compliant with IEC/EN 61643-11.
