A9F44102 and A9F18102 are two fully compatible, directly interchangeable miniature circuit breakers из серии Acti9 от Schneider Electric. Their core difference lies in product series iteration (iC60N → iC65N) and order code numbering, while their electrical parameters and mounting dimensions are almost identical.

- Key Differences
- Product Iteration
A9F44102: Legacy iC60N series, being phased out gradually.
A9F18102: Upgraded iC65N series, the official replacement for A9F44102.
Interchangeability: 100% совместимый, can be replaced directly without rewiring or adjusting installation space.
- Minor Performance Differences
Разрывная способность: The ultimate breaking capacity (Ику) of iC65N (A9F18102) reaches 50kA, higher than iC60N, providing stronger safety performance.
Physical Height: iC65N is 94mm high, slightly taller than the 85mm of iC60N, but the mounting width and depth remain the same.
- Order Code Explanation
A9F: Fixed prefix for the Acti9 series
44: Represents the iC60N series
18: Represents the iC65N series
1: 1 столб (1П)
02: Rated current 2A
- Replacement and Selection Recommendations
Direct Replacement: A9F44102 (iC60N 1P 2A) → A9F18102 (iC65N 1P 2A)
Higher Breaking Capacity: For 10kA breaking capacity, select iC65H 1P C2A (A9F27102)
Приложение: Both models are suitable for standard 2A load protection scenarios such as lighting circuits and control circuits.
