240v Surge Protection Device KYSPD-40T2-3P | Kuangya
Dispositivo de protección contra sobretensiones de 240 V for three-phase 3P (L1-L2-L3) AC networks, suitable for TN-S, TN-C, and TT systems.
Rated discharge current In 20 kA (8/20 µs), maximum discharge Imax 40 kA (8/20 µs), voltage protection level Hasta ≤ 1,3-2,0 kV en función de Uc.
Pluggable cartridge with thermal disconnector, visual fault indicator, optional RC contacts, DIN-rail mounting.
designed for three-phase systems (L1, L2, L3). It provides Type 2
protection against transient overvoltages caused by indirect lightning
and switching operations in 230/400 V AC TN-S, TN-C, and TT networks.Equipped with high-capacity MOV elements, the device ensures reliable
surge suppression with a pluggable module structure for easy service.
Integrated thermal disconnectors and clear fault indicators guarantee safety,
while optional RC contacts enable monitoring integration with building
management systems (BMS) or PLC.
