8. Infrastructure: Electrical system protection for hospitals, schools, équipements publics, ensuring public safety.
9. Renewable Energy: AC‑side protection for PV inverters and energy storage systems, suitable for new energy applications.
10. Installation & Operation Guidelines
11. Environnement: Install in dry area below 40℃, avoid moisture, corrosion, vibration; max installation altitude 2000m.
12. Câblage: 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. Entretien: Regularly check mechanism and terminals for looseness or overheating; full inspection at least once per year.
