DB-2C Lightning arrester

Applications:

The product is applicable to over-voltage protection caused by lightning, anti-electromagnetic interference, anti-higher harmonic in 220/380V, three-phase AC networks with the electricity capacity less than 1,000kVA. Especially to use to protect precision equipment in multi-level lightning protection zones.

Applicable Industries:

The telecom, broadcasting & TV,petrochemical,transportation & highway, financial industry, and government sectors at all levels.

Features：

1. Large discharge current capacity (8/20S 120kA); 2. Low residual voltage (<500V); 3. Anti-high-frequency electromagnetic wave and electromagnetic interference; 4. Improve the power factor and power load capacity; 5. Seven-mode protection design; 6. Multi-way block and current sharing technology; 7. Fault auto-off (anti-lightning module); 8. Deterioration indication and damage audible-visual alarm; 9. Clock and calendar display; 10. Network voltage monitoring; 11. Lightning time, number records; 12.RS485 or RS232 communication interface.
