SPD surge arrester /surge protector/surge protective device 100KA 

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.

Product installation:

1. SPD apply to power distribution system 380V 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 wirings must be solid and connected by  electric . SPD cable:BVR≥16mm2, grounding line: BVR ≥ 25mm2, 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.
