The A9F06232 is a 2-pole Acti9 iC60H miniature circuit-breaker rated 32 A with a B tripping curve — magnetic trip at 4 x In (±20 %). That curve B means it clears short-circuit currents fast enough to protect resistive or low-inrush loads like lighting circuits or control transformers, but it's not the right choice for motor starters where a C or D curve handles the inrush without nuisance trips. Breaking capacity hits 42 kA Icu at 133 V AC and 30 kA at 240 V AC, so it shrugs off high fault currents right at the distribution board without welding contacts shut.
Snaps onto a DIN rail — 36 mm wide (4 x 9 mm pitches), 91 mm tall, 78.5 mm deep. Double terminals top and bottom accept 1…35 mm² rigid or 1…25 mm² flexible, with a tightening torque of 3.5 N.m. Strip length is 14 mm — mark it on the wire before you crimp; too short and the conductor won't seat under the clamp.
