- Core Functions and Working Principle
- Surge Suppression Mechanism: Adopts MOV+GDT hybrid technology. MOV is responsible for fast response (≤25ns) to suppress most surges, while GDT provides higher surge withstand capacity and lower leakage current.
- Fault Indication Function: The pluggable module is equipped with a visual status indicator (green = normal, red = fault) for quick identification of protection status.
- Thermal Trip Protection: Built-in thermal trip device automatically trips when surge energy is excessive or components age, preventing overheating damage to the arrester.
- Replaceable Design: Only the pluggable trip module needs to be replaced after a fault, eliminating the need for overall replacement and reducing maintenance costs.
- Escenarios de aplicación típicos
| Application Field | Specific Application Scenario | Protection Target |
| Edificios Comerciales | Main/distribution power cabinets in office buildings, shopping malls, hoteles | Protect critical loads such as air conditioners, elevators, and lighting systems |
| Industrial Plants | Production line control circuits, PLC systems, front-end of frequency converters | Prevent damage to precision electronic equipment caused by lightning strikes or grid fluctuations |
| Centros de datos | UPS input/output terminals, front-end of server cabinet PDUs | Ensure continuous and stable operation of IT equipment and avoid data loss |
| Infrastructure | Critical power distribution circuits in hospitals and transportation hubs | Protect life-safety related equipment and control systems |
| Photovoltaic Systems | AC side output terminals of inverters | Suppress surges generated by photovoltaic systems and grid feedback surges |
- Installation and Operation Precautions
- Ubicación de instalación:
As Type 2 protección, it should be installed in the main or distribution power cabinet, after the main circuit breaker.
Recommended to be installed close to the protected equipment, with the line length not exceeding 10 metros.
- Requisitos de cableado:
Phase lines (L1/L2/L3) and neutral line (norte) must be wired correctly according to the markings.
The protective earthing (educación física) wire should be as short and thick as possible. It is recommended to use ≥16mm² copper conductors with a length not exceeding 50cm.
All terminals must be tightened to the recommended torque (8~10N·m) to prevent overheating due to poor contact.
- Matching Requirements:
A 16A~32A miniature circuit breaker or fuse must be installed upstream as overcurrent protection to prevent short circuits caused by surge arrester faults.
Not applicable to IT and TN-C earthing systems, only suitable for TN-S and TT systems.
- Puntos de mantenimiento:
Regularly check the status indicator (green = normal, red = fault).
Replace the pluggable trip module in a timely manner after a fault; do not perform plug-in operations with power on.
It is recommended to conduct a surge protection performance test every 2 años.
