Three poles protected, so it switches all three phases in a 3P AC/DC network. The 50 kA Icu at 415 V AC is the ultimate breaking capacity under IEC 60947-2; for domestic-grade coordination under IEC 60898-1, the Icn is 6 kA at 400 V. That dual rating tells you this MCB is rated for industrial panel duty (60947-2) while still carrying the residential standard mark. Clip-on mounting on a DIN rail, 54 mm wide (6 x 9 mm pitches), 85 mm tall, 78.5 mm deep — fits standard distribution boards and sub-panels. IP20 finger-safe terminals; the toggle provides local trip indication and is padlockable for lockout/tagout. ## Selectivity and coordination The thermal-magnetic trip unit handles overloads (thermal bimetal) and short circuits (solenoid) in one package; separate earth-leakage protection block can be added alongside.","metaTitle":"Schneider Electric A9F43370 Acti9 iC60N MCB, B Curve 0.5 A 3","metaDescription":"Schneider Electric A9F43370 Acti9 iC60N miniature circuit breaker, B curve, 0.5 A, 3 poles, 50 kA breaking capacity.
