The Schneider Electric A9F04132 is a 1-pole Acti9 iC60N miniature circuit breaker rated 32 A with a C-curve magnetic trip (8 x In ±20 %). The dual certification to both EN/IEC 60947-2 (industrial) and EN/IEC 60898-1 (domestic/residential) gives it a wider application envelope than a standard domestic MCB; the 60947-2 rating is the one to use for industrial panel SCCR calculations. The thermal-magnetic trip unit handles overloads (thermal bimetal) and short-circuits (magnetic coil) in one compact 18 mm wide package — two 9 mm pitches on the DIN rail. The IP20 finger-safe terminals accept up to 35 mm² rigid or 25 mm² flexible conductors, with a 3.5 N.m tightening torque and 14 mm strip length.
The 78.5 mm depth and 91 mm height fit standard distribution boards and small enclosures without crowding the gland plate. Toggle control with a visible trip indicator and contact position indicator means a quick visual check from the cabinet door confirms the breaker state without opening the cover.
