Description
The A9F74120 is a 1-pole miniature circuit breaker (MCB) from Schneider Electric’s Acti9 iC60N range, designed to provide reliable overload and short-circuit protection for both AC and DC distribution circuits. Rated at 20A with a C tripping curve, it’s well suited to general lighting and power circuits, as well as loads with moderate inrush currents, tripping magnetically at 8× the rated current (±20%).
The iC60N delivers a rated breaking capacity of 6000A (Icn) at 230V AC per EN/IEC 60898-1, and up to 10kA Icu at 220–240V AC or 36kA at 12–60V AC per EN/IEC 60947-2 — giving flexibility for both residential/commercial and industrial-style installations on the same DIN rail platform. It supports both AC and DC network types, with breaking capacities specified up to 72V DC, making it usable in low-voltage DC distribution such as control panels and battery/PV systems. Built with a compact 18mm width (1 module) for space-efficient panel design, a toggle control with clear trip indication, and top/bottom comb busbar compatibility, the A9F74120 is a dependable, multi-standard choice for general electrical distribution boards, control panels, and industrial installations.
