The Schneider Electric A9K23132 is a 1-pole Acti9 iK60N miniature circuit breaker rated 32 A at 30 °C with a B-curve (magnetic trip 3...5 x In) and 6000 A Icn breaking capacity at 230 V AC, 50/60 Hz, conforming to EN/IEC 60898-1. It clips onto a DIN rail and occupies 2 x 9 mm pitches (18 mm wide), making it a standard-fit module for distribution boards in residential and light commercial panels.
The 32 A rating at 30 °C is the continuous current the breaker carries without tripping in a 30 °C ambient — above that, thermal derating applies per the IEC curve. The B-curve trips magnetically between 3 and 5 times In (96–160 A), which suits resistive and lighting loads with low inrush; it is not intended for motor or transformer starting where C or D curves are typical. The 6000 A Icn breaking capacity at 230 V AC means the breaker can safely interrupt a fault current up to 6 kA without welding or failing, which covers most domestic and small commercial service entrances where the prospective short-circuit current stays below that level. The IP20 enclosure rating means it is touch-safe but not protected against water ingress; it belongs behind a panel door or enclosure cover.
