- Operating Principle
CVS250F-3P-250A uses thermal‑magnetic tripping protection:
- Protezione da sovraccarico (Long Time Delay): Bimetal strip bends under heat and triggers the trip mechanism. Delay decreases as current increases; Ir adjustable 175~250A.
- Short‑circuit Protection (Istantaneo): Electromagnetic coil generates strong magnetic force, attracts armature and triggers instant trip at fixed 2000A without delay.
- Caratteristica di intervento: Conforme all'IEC 60947-2, Category A for distribution protection, protects cables and equipment against overload and short‑circuit damage.
- Applicazioni tipiche
- Distribuzione dell'energia industriale: Main protection for three‑phase power equipment in factories and workshops, such as air compressors, pumps, tifosi.
- Edifici commerciali: Distribution mainline protection for offices, centri commerciali, hotels, ensuring power continuity.
- Centri dati: Power protection for UPS systems and server racks, preventing overload/short‑circuit impact on critical loads.
- Infrastructure: Electrical system protection for hospitals, schools, public facilities, ensuring public safety.
- Renewable Energy: AC‑side protection for PV inverters and energy storage systems, suitable for new energy applications.
- Installazione & Operation Guidelines
- Ambiente: Install in dry area below 40℃, avoid moisture, corrosion, vibrazione; max installation altitude 2000m.
- Cablaggio: Use copper/aluminum conductors suitable for 250A (≥95mm² copper recommended), torque per Schneider specifications.
- Protection Coordination: Coordinate with downstream breakers/fuses to ensure selective protection and avoid non‑selective tripping.
- Setting: Adjust long‑time delay current Ir (175~250A) according to load for accurate protection.
- Manutenzione: Regularly check mechanism and terminals for looseness or overheating; full inspection at least once per year.
