The Schneider Electric A9K24601 is a 1P+N miniature circuit breaker from the Acti9 iK60N series, rated 1 A with a C-curve trip characteristic. It protects final subcircuits against overloads and short circuits in AC distribution panels, with a 6 kA breaking capacity at 230 V AC per EN/IEC 60898-1. The C-curve means magnetic tripping occurs between 5 and 10 times the rated current (5–10 A), which suits moderate inrush loads like small transformers, lighting banks, and control circuits — not motor starts or high-surge gear where a D-curve would be needed.
Occupies 4 x 9 mm pitches (36 mm wide) on a DIN rail, clip-on mount. At 85 mm tall and 78.5 mm deep, it fits standard distribution boards with room for wiring access. Neutral is on the left, pole on the right — wire the incoming phase to the top terminal. Terminals accept 1–25 mm² rigid or 1–16 mm² flexible cable; strip 14 mm and torque to 2 N·m.
