2. Short‑circuit Protection (Instantaneous): Electromagnetic coil generates strong magnetic force, attracts armature and triggers instant trip at fixed 2000A without delay.
3. Tripping Characteristic: Complies with IEC 60947-2, Category A for distribution protection, protects cables and equipment against overload and short‑circuit damage.
4. 代表的な用途
5. Industrial Power Distribution: Main protection for three‑phase power equipment in factories and workshops, such as air compressors, pumps, ファン.
6. 商業ビル: Distribution mainline protection for offices, shopping malls, hotels, ensuring power continuity.
7. Data Centers: Power protection for UPS systems and server racks, preventing overload/short‑circuit impact on critical loads.
8. Infrastructure: Electrical system protection for hospitals, schools, public facilities, ensuring public safety.
9. Renewable Energy: AC‑side protection for PV inverters and energy storage systems, suitable for new energy applications.
10. インストール & Operation Guidelines
11. Environment: Install in dry area below 40℃, avoid moisture, corrosion, vibration; max installation altitude 2000m.
12. Wiring: Use copper/aluminum conductors suitable for 250A (≥95mm² copper recommended), torque per Schneider specifications.
13. 保護調整: 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. メンテナンス: Regularly check mechanism and terminals for looseness or overheating; full inspection at least once per year.
