The Kuangya KYSPD-40T2-1P is a compact type 2 surge protection device
designed for main and sub-distribution boards. It is suitable for 230/400 V AC
TN-S, TN-C, and TT networks, providing protection against transient overvoltages
caused by switching operations and indirect lightning strikes.This device uses high-capacity MOV technology, coordinated with upstream Type 1 arresters,
to ensure reliable surge suppression. The pluggable cartridge simplifies maintenance,
and the integrated thermal disconnector guarantees safety with clear green/red fault indication.
Optional RC remote contacts allow monitoring integration with BMS/PLC systems.主な特徴
