The Schneider Electric A9F03302 is a 3-pole Acti9 iC60N miniature circuit breaker rated at 2 A with a B-curve trip characteristic. This dual-standard certification (60947-2 for industrial and 60898-1 for residential/commercial) gives flexibility in panel design across both domains. The 2 A rating and B-curve (magnetic trip at 4 x In +/- 20%) suit circuits with resistive or lightly inductive loads where nuisance tripping from inrush is a concern — think lighting strings, control transformers, or small power supplies in a sub-distribution board.
The 54 mm width across 3 poles fits 6 modules of 9 mm pitch — standard for a 3-pole MCB in a distribution board. Depth is 78.5 mm, height 91 mm. The toggle control and trip indicator give clear local status.
Overvoltage category IV and pollution degree 3 ratings mean the breaker is rated for the highest surge exposure at the service entrance and can tolerate conductive dust and humidity up to 95% at 55 °C — a solid fit for industrial panels near the main incomer.
