Product Description
Single phase 25-60kA Surge Protective Device SPD

Application Scope
1. Low voltage distribution box (board) of buildings.
2. Floor distribution box of buildings.
3. Outdoor power distribution cabinet/distribution box.
4. Any place need to be waterproof, moisture proof, dustproof, rot proof.
5. Adapt to the power distribution system of 3+1/1+1 connection modes.

1.35 mm Electrical Lead Rail installation
2.8/20 µ S Wave Form, low residual voltage
3. Remote Signaling Port, remote alert
4. Build-in Over Currents Fuse Protector and Thermal Inductance Breaker
5. Degradation Automatic Release

Brief Introduction
Single Phase 25-60KA Surge Protective Device (SPD) is designed according to the IEC Standard. The maximum discharging currents (IMAX 8/20µ S) of each line could be 20-60kA. It is applicable for 220/380V Power Distribution System lightning protection in all classes.
This product adopts modular design with good tightness, working indictor, remote connector and degradation indicator. With 35 mm Electrical Lead Rail, it is convenient for connecting. With temperature control breaker, build-in over currents fuse protector and thermal inductance breaker, degradation automatic release. With advantage of extremely low residual Voltage, quick respond, large intake capacity, long working life, simple maintenance.
