That D-curve characteristic is specified for loads with high inrush, such as motor starters, transformers, or discharge lighting, where the instantaneous trip threshold must ride through the starting surge without nuisance opening. The breaking capacity is 10 kA Icn at 230 V AC per IEC 60898-1 and 10 kA Icu at 230 V AC per IEC 60947-2. Dual-rated to both standards, it qualifies for distribution boards under the household standard and for industrial panel applications under the higher-fault IEC 60947-2 regime. The 73 mm depth and 86 mm height fit the standard Acti9 modular envelope, occupying 3 x 9 mm pitches on the DIN rail. ## Deployment context Clip-on mounting to a DIN rail and tunnel terminals accepting 1 to 50 mm² rigid or 1.5 to 35 mm² flexible conductors make this MCB a straightforward panel fit. Thermal-magnetic trip technology provides overload protection via the bimetal element and short-circuit protection via the solenoid — no separate earth-leakage module is integrated, though a separate Vigi block can be added downstream.","metaTitle":"Schneider Electric A9N19828 Acti9 C120H MCB, 1P, D Curve, 12","metaDescription":"Schneider Electric A9N19828 Acti9 C120H miniature circuit-breaker, 1P, D curve, 125 A rated current, 10 kA breaking capacity at 230 V AC.
