Type 2 surge protection device KYSPD-40T2-1P | Kuangya
Dispositif de protection contre les surtensions de type 2 for 230/400 V AC single-phase and three-phase systems.
Rated discharge current En 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 DIN-rail module, thermal disconnector with green/red status, optional RC remote contacts.
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.
