Breaking capacity is 5 kA Icu at 230…400 V AC 50/60 Hz per EN/IEC 60947-2, which is the standard for distribution boards in commercial and light industrial panels where the prospective fault current stays under that level. The thermal-magnetic trip unit combines a bimetal for overload protection and a solenoid for short-circuit; D curve gives a wider magnetic band than B or C, so it fits motor feeders, welding equipment, or power supplies with large input capacitors. Tunnel terminals accept 1…50 mm² rigid or 1.5…35 mm² flexible cable; strip length 15 mm, torque to 3.5 N·m. IP20 finger-safe protection on the front, so it's suitable for open-panel installation inside a locked enclosure.","metaTitle":"Schneider Electric A9N60721 Acti9 C120 MCB, 1P D Curve 100 A","metaDescription":"Schneider Electric A9N60721 Acti9 C120 miniature circuit breaker, 1-pole, D curve, 100 A rated current, 5 kA breaking capacity at 400 V AC.
