The D curve means its magnetic trip threshold is 10–14× In, suited for loads with high inrush current like motors or transformers — the breaker holds through the start-up spike and trips only on sustained overload or short circuit. ## Deployment Context The clip-on mounting and 6-module width (9 mm pitches) fit standard DIN-rail enclosures. The 73 mm depth leaves clearance for shallow gland plates. Rated for isolation (suitability for isolation: yes) with a contact position indicator, so it doubles as a visible-break disconnect in distribution panels.","metaTitle":"A9N19805 Acti9 C120H MCB, 2P, 63A, D Curve, 10kA","metaDescription":"Schneider Electric A9N19805 Acti9 C120H miniature circuit breaker, 2P, 63A, D curve, 10kA breaking capacity.
