Thermal-magnetic trip unit, 50 kA Icu breaking capacity at 380–415 V AC, and dual-certified to EN/IEC 60898-1 and EN/IEC 60947-2. Clip-on DIN-rail mount, IP20 finger-safe terminals. Curve D (magnetic trip at 12 x In ±20 %) means this breaker tolerates the high inrush of motor starters, small transformers, or solenoid banks without nuisance tripping — at 0.5 A, the magnetic threshold fires between 4.8 A and 7.2 A. The 50 kA Icu at 380–415 V AC is the maximum fault current it can safely interrupt once; for repeated clearing, the Ics (service breaking capacity) is typically 50 % of Icu per IEC 60947-2, so plan coordination accordingly. Rated insulation voltage 500 V AC, operational voltage up to 440 V AC / 180 V DC. ## Panel integration Clip-on mount to standard 35 mm DIN rail. Width 54 mm (6 x 9 mm pitches), height 85 mm, depth 78.5 mm. Terminals accept 1–25 mm² rigid or 1–16 mm² flexible, strip length 14 mm, torque to 2 N·m. Padlockable toggle, trip indicator, and separate earth-leakage block provision.","metaTitle":"Schneider Electric A9F45370 iC60N MCB, Curve D, 0.5 A, 3P","metaDescription":"Schneider Electric A9F45370 iC60N miniature circuit breaker, 0.5 A, 3-pole, curve D, 50 kA breaking capacity.
