The Schneider Electric A9F68210 is a 10 A, C-curve, 2-pole miniature circuit breaker from the Acti9 iT60 series. Breaking capacity is the key selection parameter here. The A9F68210 carries 36 kA Icu at 12–133 V AC, 20 kA at 220–240 V, 10 kA at 380–415 V, and 6 kA at 440 V per EN/IEC 60947-2. That 10 kA at 400 V covers most panelboard applications; the 20 kA at 240 V gives headroom for high-fault service entrances.
Panel integration
Mounts on DIN rail with a removable comb busbar installed. Terminals accept 1–25 mm² rigid or 1–16 mm² flexible wire; tightening torque is 2 N·m. The IP20 B finger-safe terminals meet IEC 60529 for panel interior use. The toggle actuator and trip indicator give local visual status.
