Type 1 Surge Protective Device 1+1 KYSPD-25T1-1+1 | Kuangya
Type 1 surge protective device 1+1 diseñado para single-phase TN/TT systems at 230 V AC.
Surge ratings: Iimp 12.5 kA (10/350 µs), In 20 kA (8/20 µs), Up ≤ 1.5–2.0 kV en función de Uc.
Combines MOV for L–N y GDT for N–PE, pluggable modules, thermal disconnector, optional RC contacts.
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.
