4. Aplicações Típicas
5. Distribuição de energia industrial: Main protection for three‑phase power equipment in factories and workshops, such as air compressors, bombas, fãs.
6. Edifícios Comerciais: Distribution mainline protection for offices, shoppings, hotels, ensuring power continuity.
7. Centros de dados: Power protection for UPS systems and server racks, preventing overload/short‑circuit impact on critical loads.
8. Infrastructure: Electrical system protection for hospitals, schools, instalações públicas, ensuring public safety.
9. Renewable Energy: AC‑side protection for PV inverters and energy storage systems, suitable for new energy applications.
10. Instalação & Diretrizes de Operação
11. Ambiente: Install in dry area below 40℃, avoid moisture, corrosion, vibração; max installation altitude 2000m.
12. Fiação: Use copper/aluminum conductors suitable for 250A (≥95mm² copper recommended), torque per Schneider specifications.
13. Protection Coordination: Coordinate with downstream breakers/fuses to ensure selective protection and avoid non‑selective tripping.
14. Setting: Adjust long‑time delay current Ir (175~250A) according to load for accurate protection.
15. Manutenção: Regularly check mechanism and terminals for looseness or overheating; full inspection at least once per year.
