Type 2+3 Surge Protective Device 3P KYSPD-20T2+3-3P | Kuangya
Type 2+3 surge protective device 3P para three-phase (L1-L2-L3) 230/400 V AC networks.
Surge ratings: In 10 kA (8/20 µs), Imax 20 kA (8/20 µs), Up ≤ 0.3–1.8 kV depending on Uc.
Compact pluggable DIN-rail design, thermal disconnector with indicator, optional RC monitoring contacts.
designed for three-phase AC distribution systems at 230/400 V. It integrates Type 2
and Type 3 protection classes, providing coordinated surge suppression for
equipment sensitive to transient overvoltages from switching operations or lightning.The SPD uses MOV-based modules with pluggable cartridges for easy maintenance.
Integrated thermal disconnectors with visible fault indicators ensure safe operation,
while optional RC contacts allow remote fault monitoring and integration with building
management systems or control circuits.
