The Schneider Electric A9K24613 is a 1P+N miniature circuit breaker from the Acti9 iK60N series, rated 13 A at 30 °C with a C-curve magnetic trip (5...10 x In). The 1P+N configuration switches the phase and breaks the neutral, but only the phase is protected (one protected pole). The neutral is switched but not monitored for overload — standard for single-phase final circuits where the neutral is not expected to carry imbalance current.
Clip-on mounting to DIN rail (35 mm per EN 60715). Depth is 78.5 mm, height 85 mm. Tunnel terminals accept 1...25 mm² rigid or 1...16 mm² flexible copper; tighten to 2 N.m. Strip 14 mm of insulation. Pollution degree 2 (non-conductive dust, occasional condensation) matches typical indoor panel conditions. Overvoltage category II applies, so it is intended for fixed-installation socket and lighting circuits, not for incoming mains or utility metering.
