SLV-10S/SLV-20S is a compact ultra-low residual voltage surge protector designed for single-phase power supply systems, ideal for fine lightning protection in LPZ 1-2 and subsequent lightning protection zones.
As a series-installed fine arrester at the front end of equipment, it integrates full-mode protection to shield against surges in line-neutral, line-earth, and neutral-earth paths.
With nominal discharge current of 10kA (SLV-10S) and 20kA (SLV-20S), this SPD efficiently diverts transient overvoltages caused by lightning or power grid fluctuations.
The "no leakage current, no afterflow" design ensures energy efficiency and operational safety, while the ultra-low residual voltage minimizes impact on sensitive devices.
| Product features |
● Full mode protection |
● Large flow capacity and super low residual pressure |
● No leakage current, no afterflow |
● Suitable for installation in LPZ 1-2 and subsequent lightning protection zones, used for single-phase power supply systems, and a fine lightning arrester installed in series at the front level of the equipment. |

Notices
● Confirm that the system voltage matches 220Vac(50Hz) before installation.
● Use wiring with cross-sectional area 2.5mm²-10mm² and fasten screws to 3N·m torque.
● Grounding wire length should be less than 0.5 meters to optimize protection effect.
● Replace the SPD immediately if the LED indicator turns red (failure status).
● Do not exceed the maximum load current (20A) to avoid overheating.
● This product is for indoor use only; avoid exposure to moisture or direct sunlight.
