It clips onto DIN rail and is rated for distribution duty in residential, commercial, or light industrial panels. The 80 A rating at 30 °C sets the continuous current it can carry without tripping — sized for a feeder or submain, not a final branch circuit. Dual-standard compliance with EN/IEC 60898-1 and 60947-2 means it qualifies for both MCB and industrial circuit-breaker applications — useful when a panel spec calls for the higher IEC 60947-2 ratings. Clip-on mounting to DIN rail — standard 35 mm rail. The tunnel terminals accept 1–50 mm² rigid or 1.5–35 mm² flexible, so it handles the larger cable sizes an 80 A circuit demands. The toggle gives local ON/OFF indication, and the contact position indicator confirms the state visually — useful during panel commissioning or fault isolation.","metaTitle":"Schneider Electric A9N19812 Acti9 C120H MCB, 1P, 80A, D Curv","metaDescription":"Schneider Electric A9N19812 Acti9 C120H MCB, 1P, 80A, D curve, 10 kA breaking capacity.
