3. External wiring terminal, easy for connection, suitable for indoor or outdoor application.
4. Built EMI filter function.
5. Mode of protection：L-PE;N-PE.
High Surge Currents: Imax=100kA(8/20μs)
Lightning Protection Device is designed to control high-energy transient voltage caused by lightning activity. Installed at power entry points or designated distribution locations, it limits surge energy before it reaches internal circuits and connected systems. The device remains active during normal electrical operation and supports continuous power flow. It is suitable for electrical systems exposed to outdoor lines or elevated lightning risk. By managing surge energy at the entry stage, it helps reduce electrical stress on wiring, panels, and equipment, supporting safer operating conditions across protected installations.
Features
1. Lightning Surge Limiting: Controls high-energy voltage spikes generated by lightning events.2. Fast Electrical Reaction: Responds quickly when sudden overvoltage conditions appear.
3. High-Energy Handling Capacity: Designed to manage strong surge levels from external sources.
4. Defined Voltage Clamping Range: Keeps voltage within preset electrical thresholds.
5. Panel and Entry Installation: Suitable for placement at power entry or distribution panels.
6. Continuous Protection State: Remains active during normal electrical operation.
Advantages
1. Equipment Damage Reduction: Lowers lightning-related voltage stress on electrical devices.2. Circuit Protection Support: Helps reduce surge impact on internal wiring systems.
3. Entry-Level Voltage Control: Manages abnormal voltage before distribution across circuits.
4. Broad System Coverage: Protects multiple circuits through centralized installation.
5. Suitable for Repeated Exposure: Designed for environments with frequent lightning activity.
6. Simple Electrical Integration: Fits existing power layouts without major system changes.
Applications
1. Power Entry Points: Surge control where external lines enter electrical systems.2. Electrical Distribution Panels: Protects downstream circuits from lightning-related surges.
3. Industrial Power Systems: Suitable for facilities exposed to outdoor power lines.
4. Commercial Buildings: Supports lightning surge control for building power networks.
5. Telecommunication Power Supplies: Protects equipment connected to exposed supply lines.
6. Outdoor Electrical Installations: Applied in systems with elevated lightning exposure risk.
