A9F74120 Schneider Electric – Acti9 iC60N Miniature Circuit Breaker (MCB), 1P, 20 A, C Curve, 6 kA / 10 kA
The Schneider Electric A9F74120 is a single-pole Acti9 iC60N miniature circuit breaker rated 20 A with a C tripping curve. That makes it the standard choice for protecting circuits with moderate inrush currents, such as small motors, transformers, lighting and general power circuits in commercial and industrial installations. It is rated 6000 A to IEC/EN 60898-1 and 10 kA to IEC/EN 60947-2, and it protects against both overload and short circuit on AC and DC networks.
