- Aplicații tipice
- Distribuția de energie industrială: Main protection for three‑phase power equipment in factories and workshops, such as air compressors, pompe, fani.
- Clădiri Comerciale: Distribution mainline protection for offices, centre comerciale, hoteluri, ensuring power continuity.
- Centre de date: Power protection for UPS systems and server racks, preventing overload/short‑circuit impact on critical loads.
- Infrastructură: Electrical system protection for hospitals, scoli, facilitati publice, ensuring public safety.
- Energie regenerabilă: AC‑side protection for PV inverters and energy storage systems, suitable for new energy applications.
- Instalare & Ghid de operare
- Mediu: Install in dry area below 40℃, avoid moisture, corrosion, vibratie; max installation altitude 2000m.
- Cablaj: Use copper/aluminum conductors suitable for 250A (≥95mm² copper recommended), torque per Schneider specifications.
- Coordonarea protecției: Coordinate with downstream breakers/fuses to ensure selective protection and avoid non‑selective tripping.
- Setare: Adjust long‑time delay current Ir (175~250A) according to load for accurate protection.
- Întreţinere: Regularly check mechanism and terminals for looseness or overheating; full inspection at least once per year.
