1) Product Description：
This product is a three-phase parallel connection power surge protector device (called: SPD).This product is designed as modular with artistic outline, easy wire connection and simple installation, simple maintenance, working in a relatively harsh environment and maintaining in a long-term stability. SPD can effectively prevent overvoltage and over current which are induced by lightning or industrial noise and other factors, and other transient surge voltage on the system or equipment or cause permanent damage or momentarily interruption and other hazards.
◆SPD is use to lightning protection zone: LPZ0 area at the junction with the LPZ1 (B class) power lines of the lightning surge protection.
◆It has work instructions function, indicate deterioration module functions, green (normal), red (failure).
◆ SPD is designed as modular with good tightness, working indictor and degradation indicator. It is convenient for connecting.
◆With temperature control breaker function, build-in over currents fuse protector, completely avoid the fire.
◆This unit has lots of advantages: such as: extremely quick respond, large intake capacity, small leakage power, long working life, simple maintenance. It is especially suitable for harsh lightning environments.
◆It is use for lightning protection of AC power distribution equipment, such as communication, television broadcasting, computer room, automatic control, and mechanical equipment and all distribution equipment protection.
 3) Product Installation:
1.SPD apply to power distribution system first-level lightning protection, it is installed in parallel on into the line side of the total power distribution equipment or the power distribution box in the buildings, with 35mm electrical lead rail, Kevin connections can be used. Cut off the power before installation, strictly prohibit powered operation.
2.Before installation please according to installation diagram of connections, including L1, L2, L3 all are the phase line, N is zero line, PE is ground line, please connect correctly. When installation is complete, close the automatic circuit breaker, check the working condition is normal or not.
3.During using lightning protection module, we should monitored and check the status display window regularly, when the display window was red or remote terminal output signal, it means the lightning protection module failure, it should be promptly repaired or replaced.
4. Apply to indoor operation, such as outdoors installation, you must install waterproof shell.
5. All wiring must be solid and connect by electric. SPD cable: BVR≥10mm2, grounding line: BVR ≥ 16mm2, the lead length should be less than 1m and the shorter the better.
6 .Lightning proof grounding should be consistent with lightning protection regulatory requirements, grounding wire should be as thick and short as possible, resistance should be less than 10Ω.
