7. Standard Mounting: DIN rail mounting with 1-module width, saving switchgear space, and compatible with Acti9 series accessories (例えば, auxiliary contacts, alarm contacts).
8. 環境適応力: IP20 protection rating, resistant to temperatures ranging from -25℃ to 70℃, meeting the requirements of industrial and civil distribution environments.
9. Application Scope

– Overload and short-circuit protection for single-phase distribution circuits of lighting, ソケット, small motors, 等, in commercial buildings and industrial plants.

Places with high requirements for power supply reliability, such as office buildings, hotels, and hospitals.

Compatible with Acti9 series distribution boxes, used in scenarios such as terminal power distribution and branch circuit protection.

5. Selection Recommendations
6. ロードマッチング: Type C curve is suitable for non-inductive loads (例えば, lighting, ソケット); avoid selecting Type D (for power loads) or Type B (for electronic equipment) curves.
7. Circuit Matching: With a rated current of 6A, it is suitable for 1.5mm² copper core cables (long-term current-carrying capacity ≥ 10A), and the circuit length should be ≤ 100m.
8. 遮断容量: The 6kA breaking capacity is suitable for terminal distribution; the front-end should be equipped with molded case circuit breakers with higher breaking capacity (例えば, 15kA and above).
9. Accessory Selection: According to monitoring requirements, select accessories such as auxiliary contacts (例えば, A9A26924) and alarm contacts (例えば, A9A26934).
10. トラブルシューティング

7. Alternative Solutions

Intra-series Alternatives: A9P52610 (1P+N, 10あ, タイプC), A9P52616 (1P+N, 16あ, タイプC), 等, maintaining mounting and accessory compatibility.

Cross-series Alternatives: Schneider Electric IDPN series (例えば, A9D18606, 1P+N, 6あ, タイプC) or ABB S200 series (例えば, S201M‑C6, 1P+N, 6あ, タイプC). It is necessary to verify the matching of mounting dimensions and breaking capacity.
