A9F44102 and A9F18102

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

3. Product Iteration

A9F44102: Legacy iC60N series, sendo gradualmente eliminado.

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

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

2. Minor Performance Differences

Quebrando Capacidade: The ultimate breaking capacity (UTI) 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 pólo (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)

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