The Kuangya KYSPD-25T1-1+1 is a type 1 surge protective device 1+1
designed for installation at the service entrance of low-voltage AC systems.
It uses a 1+1 topology: MOV protection between L–N and coordinated GDT protection
between N–PE, ensuring effective discharge of lightning current impulses (10/350 μs).It is ideal for main distribution boards in residential, commercial, and industrial
buildings, providing primary protection against direct lightning strikes and high-energy surges.
The pluggable cartridge design simplifies replacement, while integrated thermal disconnectors
and status indicators ensure safe operation. Optional RC contacts enable remote monitoring.주요 기능
