A9F74125 Schneider Electric – Acti9 iC60N MCB, 1 Pole, 25 A, C Curve, 6000 A (IEC 60898-1) / 10 kA (IEC 60947-2)
The A9F74125 is the 25 A, single-pole, C-curve version of Schneider Electric’s Acti9 iC60N miniature circuit breaker. It sits one step above the 20 A rating and is typically used for heavier final circuits: larger socket-outlet circuits, small heating loads, HVAC units, single-phase motors and sub-distribution feeds. The C tripping curve tolerates the moderate inrush currents of motors and transformers without nuisance tripping, while still clearing short circuits quickly.

Mounting, Wiring and Dimensions
The breaker is a single 18 mm module (85 × 78.5 mm) that clips onto a DIN rail. It accepts comb busbars at the top or bottom. Its terminals take 1–25 mm² rigid or 1–16 mm² flexible conductors, with a 14 mm stripping length and a 2 N·m tightening torque. A trip indicator and positive contact indication show the breaker’s state at a glance.
Operating Environment
- Operating temperature: −35 to 70 °C
- Protection: IP20
- Pollution degree: 3
- Overvoltage category: IV
- Durability: 20,000 mechanical / 10,000 electrical cycles
Compliance
The breaker complies with IEC/EN 60898-1 and IEC/EN 60947-2 and carries the NF mark. It is a Schneider Electric Green Premium product, RoHS and REACH compliant.
