The 4-pole (4P) construction isolates all phases and neutral in a single module, saving DIN-rail space compared to separate breakers. Breaking capacity hits 36 kA Icu at 12–133 V AC and still holds 10 kA Icu at 380–415 V AC, so it handles high-fault panels without cascading upstream. Dual-certified to EN/IEC 60947-2 (industrial) and EN/IEC 60898-1 (residential/commercial), which means it qualifies for both distribution boards and industrial control panels — one part number for mixed environments. Snaps onto standard DIN rail — 9 mm pitch, 8 modules wide (72 mm). The double terminals accept 1–25 mm² rigid or 1–16 mm² flexible on top or bottom, with a 14 mm strip length and 2 N·m tightening torque. IP20 finger-safe terminals keep live parts covered during commissioning. Overvoltage category IV means it can be installed at the service entrance, not just downstream sub-panels. ## Durability and environmental specs Rated for 10,000 electrical cycles and 20,000 mechanical cycles — enough for frequent switching in lighting or motor control circuits. The thermal-magnetic trip unit provides both overload protection (thermal bimetal) and short-circuit protection (magnetic solenoid) in one compact package. Earth-leakage protection requires a separate Vigi block, not built in.","metaTitle":"Schneider Electric A9F03425 Acti9 iC60N MCB, 25 A, 4P, B-Cur","metaDescription":"Schneider Electric A9F03425 Acti9 iC60N miniature circuit-breaker, 25 A rated current, 4 poles, B-curve, 36 kA breaking capacity.
