Schneider Acti9 iC60N A9F74120 1P 20A C-Curve 6kA MCB
Schneider Electric A9F74120 is an Acti9 iC60N single-pole C-curve thermal-magnetic breaker rated 20A for overload and short-circuit protection. It provides 6kA Icn at230VAC under EN/IEC60898-1 and 10kA Icu and7.5kA Ics at220–240VAC under EN/IEC60947-2. Its18mm DIN-rail body includes contact-position and trip indication. Voltage-specific AC/DC ratings must be observed; earth-leakage protection requires a separately selected compatible add-on.
