Surge Protective Device Type 3 KYSPD-T3-2P | Kuangya
Surge protective device type 3 for single-phase 2P (L+N) 230 V AC systems.
Surge ratings: In 3 kA (8/20 µs), Imax 6 kA (8/20 µs), Up ≤ 1.0–1.5 kV depending on Uc.
Compact module for terminal equipment protection, quick DIN-rail mounting, optional RC signaling contacts.
designed for fine protection of sensitive equipment at the terminal level of electrical
systems. It is applied in 230 V single-phase networks, safeguarding electronics,
computers, communication devices, and control circuits against transient surges.Using MOV-based suppression elements, this SPD offers reliable performance
with fast response time, compact size, and DIN-rail installation.
Integrated thermal disconnectors and visible fault indicators ensure safety,
while optional RC contacts provide remote fault monitoring.
