Three-phase modular type power SPD
Product Description
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 overcurrent 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.
◆ The product apply to lightning protection zone: LPZ2 area at the junction with the LPZ3 (D class) power lines (380V) of the lightning surge protection.
◆ With work instructions, indicate deterioration module functions, green (normal), red (failure).
◆ This product is designed as modular with good tightness ,working indictor and degradation indicator. It is convenient for connecting.
◆With temperature control breaker, build-in over currents fuse protector , completely avoid the fire.
◆With advantage of extremely quick respond, large intake capacity,small leakage power ,
long working life, simple maintenance.It is especially suitable for harsh lightning environments.
◆Apply to distribution of electric box or floor distribution box; public places outdoor power distribution room, power distribution cabinets (boxes); room. Distribution box or the power supply front; residential building units a form of a distribution box; room information systems applicable to Class C power distribution box protection; apply to industrial plant electrical distribution box (cabinet) of power protection. It can be used with class B and class C, class D of the SPD.

3)Product installation:
1. SPD apply to power distribution system 380V third-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 wirings must be solid and connected by electric . SPD cable:BVR≥6mm2, grounding line: BVR ≥ 10mm2, the lead length should be less than 1m and the shorter the better.
6. Lightningproof 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.
