Type 2+3 Surge Protective Device for Equipment KYSPD-20T2+3-1+1 | Kuangya
Type 2+3 surge protective device for equipment, conçu pour single-phase 230 V AC systems.
Surtensions : En 10 kA (8/20 µs), Imax 20 kA (8/20 µs), Up ≤ 1.5 kV en fonction de Uc.
1+1 topology (L–N MOV + N–PE GDT) for coordinated equipment-level protection, pluggable cartridge, optional RC contacts.
specifically designed to protect sensitive electronic and electrical devices connected to single-phase 230 V AC systems.
It combines Type 2 protection against switching surges with Type 3 fine protection for terminal equipment.The SPD uses a 1+1 topology, employing MOV suppression between L–N and a GDT discharge path between N–PE.
Its pluggable module design ensures easy maintenance, while integrated thermal disconnectors and status indicators enhance operational safety.
Optional RC contacts provide remote fault signaling for monitoring systems.
