The Schneider Electric A9D37232 is an Acti9 iC60 RCBO — a combined residual-current circuit breaker with overcurrent protection in one 36 mm-wide, 2-pole module. It carries a 32 A rated current (In) with a B-curve magnetic trip (3 to 5 × In), and integrated 30 mA earth-leakage protection. The unit is rated for 10 kA Icn at 220–240 V AC, 50 Hz per EN/IEC 61009-2-1, with a 15 kA Icu per EN/IEC 60947-2. This is a thermal-magnetic trip device, so it responds to both overload (thermal) and short-circuit (magnetic) events, plus residual ground-fault currents down to 30 mA.
Clip-on mounting to DIN rail, 4 pitches at 9 mm between poles — so it occupies 36 mm of rail width. The tunnel-type terminals accept 1–35 mm² rigid or 1–25 mm² flexible cable, with a 2 N·m tightening torque and 12 mm strip length. IP40 in a distribution enclosure, IP20 bare. The toggle provides local signalling for ON, OFF, and fault-trip status. Intended as an outgoer device in a final distribution circuit.
