Type 2 Surge Protection Device 4P KYSPD-40T2-4P | Kuangya
Type 2 surge protection device 4P for three-phase + N (L1-L2-L3-N) AC systems.
Rated discharge current In 20 kA (8/20 µs), maximum discharge Imax 40 kA (8/20 µs), voltage protection level Up ≤ 1.3–2.0 kV (depending on Uc).
Pluggable cartridge, thermal disconnector with fault indicator, optional RC contacts, DIN-rail mounting.
designed for three-phase systems with neutral (L1, L2, L3, N). It offers reliable
protection against switching surges and indirect lightning strikes in 230/400 V AC
TN-S and TT networks.Using high-energy MOV elements, this device provides robust surge protection
with pluggable replaceable modules. Integrated thermal disconnectors ensure safe
operation, while clear green/red indicators display status. Optional RC contacts
allow monitoring integration with BMS or PLC systems.
