- Functional Features
- 1P+N Design: Live wire protection plus synchronous neutral wire switching, suitable for single-phase distribution systems, with clear wiring and convenient maintenance.
- Type C Tripping Curve: Suitable for conventional loads such as lighting and sockets, balancing overload time-delay and short-circuit instantaneous tripping, with strong resistance to inrush current.
- High Breaking Capacity: 6kA (IEC 60947‑2)/4.5kA (EN 60898‑1), capable of handling severe short-circuit faults and ensuring distribution safety.
- Standard Mounting: DIN rail mounting with 1-module width, saving switchgear space, and compatible with Acti9 series accessories (e.g., auxiliary contacts, alarm contacts).
- Environmental Adaptability: IP20 protection rating, resistant to temperatures ranging from -25℃ to 70℃, meeting the requirements of industrial and civil distribution environments.
- Application Scope
– Overload and short-circuit protection for single-phase distribution circuits of lighting, sockets, small motors, etc., 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.
- Selection Recommendations
- Load Matching: Type C curve is suitable for non-inductive loads (e.g., lighting, sockets); avoid selecting Type D (for power loads) or Type B (for electronic equipment) curves.
- 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.
- Breaking Capacity: The 6kA breaking capacity is suitable for terminal distribution; the front-end should be equipped with molded case circuit breakers with higher breaking capacity (e.g., 15kA and above).
- Accessory Selection: According to monitoring requirements, select accessories such as auxiliary contacts (e.g., A9A26924) and alarm contacts (e.g., A9A26934).
- Troubleshooting
| Fault Phenomenon | Possible Causes | Troubleshooting Methods |
| Frequent Tripping | Overload, line grounding/short-circuit, mismatched tripping curve | Check load current and insulation resistance; replace MCB with a matching tripping curve |
| Failure to Close | Unreset tripping mechanism, line short-circuit, contact ablation | Manually reset the trip lever, locate the short-circuit point, replace damaged contacts |
| Excessive Temperature Rise | Loose wiring, contact oxidation, high ambient temperature | Tighten wiring terminals, polish contacts, improve ventilation and heat dissipation |
| Insufficient Breaking Capacity | Lack of front-end protection, excessive short-circuit current in the line | Upgrade front-end protection, select MCB with higher breaking capacity |
- Alternative Solutions
Intra-series Alternatives: A9P52610 (1P+N, 10A, Type C), A9P52616 (1P+N, 16A, Type C), etc., maintaining mounting and accessory compatibility.
Cross-series Alternatives: Schneider Electric IDPN series (e.g., A9D18606, 1P+N, 6A, Type C) or ABB S200 series (e.g., S201M‑C6, 1P+N, 6A, Type C). It is necessary to verify the matching of mounting dimensions and breaking capacity.
