Type 1+2 Surge Protection Device Single Phase KYSPD-7T1+2-1+1 | Kuangya
Type 1+2 surge protection device single phase, designed for 230 V AC 1+1 topology (L–N MOV + N–PE GDT).
Surge ratings: Iimp 7 kA (10/350 µs), In 20 kA (8/20 µs), Up ≤ 1.5–2.0 kV.
Compact pluggable module, thermal disconnector with fault indicator, optional RC contacts.
designed for installation at the service entrance of 230 V AC systems.
It provides combined Type 1 and Type 2 protection, capable of discharging high-energy
lightning impulses (10/350 μs) as well as switching surges (8/20 μs).
Using a 1+1 topology with MOV protection between L–N and coordinated GDT
protection between N–PE, this SPD ensures comprehensive protection for residential,
commercial, and industrial electrical installations. Its pluggable cartridge design
simplifies replacement, while integrated thermal disconnector and visible indicator
guarantee safe operation. Optional RC contacts enable remote monitoring.
