The A9D50232 is a 2-pole RCBO (residual-current circuit breaker with overcurrent protection) from the Acti9 iC60 family, rated 32 A with a C-curve trip characteristic — meaning the magnetic release operates between 5 and 10 times the rated current (160–320 A), per the datasheet. The integrated earth-leakage protection trips at 300 mA sensitivity, which is the standard threshold for protection against fire risk from ground faults in fixed wiring — not personnel protection (that calls for 30 mA). The breaking capacity is 10 kA Icn per EN/IEC 61009-2-1 at 220–240 V AC, 50 Hz, with an ultimate breaking capacity (Icu) of 15 kA per EN/IEC 60947-2. The limitation class is 3 per EN/IEC 61009-2-1, which limits let-through energy under short-circuit conditions — relevant when coordinating with downstream equipment. The thermal-magnetic trip unit gives a time-delayed response on overloads and instantaneous magnetic trip on shorts. Per the datasheet, the electrical durability is 5000 cycles and mechanical durability 20,000 cycles, so this is a distribution-grade device, not a switching-duty contactor.
Clip-on mounting to DIN rail per EN/IEC 60715. The 2-pole device occupies 4 modules of 9 mm pitch (36 mm total width), so it fits a standard 18-module distribution board with room for adjacent devices. Tunnel-type terminals accept 1–35 mm² rigid or 1–25 mm² flexible conductors; wire stripping length is 12 mm for top or bottom connection.
