- 主な違い
- Product Iteration
A9F44102: Legacy iC60N series, being phased out gradually.
A9F18102: Upgraded iC65N series, the official replacement for A9F44102.
Interchangeability: 100% compatible, can be replaced directly without rewiring or adjusting installation space.
- Minor Performance Differences
遮断容量: 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.
- Order Code Explanation
A9F: Fixed prefix for the Acti9 series
44: Represents the iC60N series
18: Represents the iC65N series
1: 1 ポール (1P)
02: Rated current 2A
- Replacement and Selection Recommendations
直接交換: A9F44102 (iC60N 1P 2A) → A9F18102 (iC65N 1P 2A)
Higher Breaking Capacity: For 10kA breaking capacity, select iC65H 1P C2A (A9F27102)
応用: Both models are suitable for standard 2A load protection scenarios such as lighting circuits and control circuits.
