The Kuangya KYSPD-T3-2P is a dedicated surge protective device type 3
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.主な特徴
- Type 3 SPD according to IEC/EN 61643-11 (Class III protection).
- Nominal discharge current (In): 3 kA (8/20 μs).
- Maximum discharge current (Imax): 6 kA (8/20 μs).
- Voltage protection level (Up): ≤ 1.0–1.5 kV depending on Uc.
- Response time < 25 ns for rapid surge suppression.
- Back-up fuse: max 32 A gL/gG; ISCCR 6 kA AC.
- Compact 2P design for terminal or downstream protection.
- Optional RC contacts for remote signaling (AC 250 V / 0.5 A; DC 250 V / 0.1 A).
- Housing IP20, UL94 V-0 thermoplastic; operating temperature -40 °C to +70 °C.
- 35 mm DIN rail mounting; IEC/EN 61643-11 compliant.
