The Schneider Electric A9F04225 is an Acti9 iC60N miniature circuit breaker, rated 25 A, 2 poles, with a C-curve trip characteristic. It carries a 36 kA Icu breaking capacity at 12-133 V AC (per EN/IEC 60947-2) and a 10 kA Icn at 400 V AC (per EN/IEC 60898-1), making it suitable for distribution panel final circuits in commercial and light industrial builds.
The 25 A C-curve means the magnetic trip activates between 5 and 10 times rated current (8 x In +/-20 % per spec), so it handles moderate inrush from motorized or fluorescent loads without nuisance tripping. Thermal-magnetic trip technology means bimetal for overload, solenoid for short-circuit — no electronics to fail. Overvoltage category IV and pollution degree 3 mean it's rated for the mains entrance of an installation — not just downstream sub-distribution. The IP20 finger-safe terminals suit enclosed panel mounting, not wet or dusty environments.
Width is 36 mm (4 x 9 mm pitches), height 91 mm, depth 78.5 mm. Snaps onto standard DIN rail. The double terminals accept 1-25 mm² rigid or 1-16 mm² flexible, with a 2 N.m tightening torque and 14 mm strip length. Trip indicator shows local status; toggle control with contact position indicator for isolation verification (suitability for isolation confirmed per both standards).
