A9F44102 and A9F18102

A9F44102 and A9F18102 are two fully compatible, directly interchangeable miniature circuit breakers de la série Acti9 de 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.

1. Model and Core Parameter Comparison

2. Différences clés
3. Product Iteration

A9F44102: Legacy iC60N series, progressivement supprimé.

A9F18102: Upgraded iC65N series, the official replacement for A9F44102.

Interchangeability: 100% compatible, can be replaced directly without rewiring or adjusting installation space.

2. Minor Performance Differences

Capacité de coupure: The ultimate breaking capacity (ICU) 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.

3. Order Code Explanation

A9F: Fixed prefix for the Acti9 series

44: Represents the iC60N series

18: Represents the iC65N series

1: 1 pôle (1P.)

02: Rated current 2A

3. 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)

Application: Both models are suitable for standard 2A load protection scenarios such as lighting circuits and control circuits.
