- 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.
- Protezione termica: 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.
- Scenari applicativi tipici
| Campo di applicazione | Specific Application Scenario | Protection Target |
| Edifici commerciali | Main/distribution power cabinets in office buildings, centri commerciali, Hotel | Protect critical loads such as air conditioners, ascensori, e sistemi di illuminazione |
| Impianti Industriali | Production line control circuits, PLC systems, front-end of frequency converters | Prevent damage to precision electronic equipment caused by lightning strikes or grid fluctuations |
| Centri dati | UPS input/output terminals, front-end of server cabinet PDUs | Ensure continuous and stable operation of IT equipment and avoid data loss |
| Infrastrutture | 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 |
- Precauzioni per l'installazione e il funzionamento
- Posizione di installazione:
As Type 2 protezione, 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 metri.
- Requisiti di cablaggio:
Phase lines (L1/L2/L3) and neutral line (N) must be wired correctly according to the markings.
The protective earthing (PE) 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.
- Punti di manutenzione:
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 anni.
