It snaps onto a DIN rail, so panel integration is straightforward: 72 mm wide, 91 mm tall, 78.5 mm deep, occupying 8 x 9 mm pitches on the rail. The C-curve magnetic trip fires at 8 x In ±20 % — meaning it holds through moderate inrush (common with small motors, transformers, or lighting ballasts) and clears fast on a hard short. That 50 A rating on a 4-pole frame handles three-phase plus neutral, rated for distribution duty (Category A per EN/IEC 60947-2). Breaking capacity is the headline number here: 42 kA Icu at 12–133 V AC, 30 kA at 220–240 V, 15 kA at 380–415 V, and 10 kA at 440 V AC (per IEC 60947-2). For IEC 60898-1 the Icn is 15 kA at 400 V AC, so the part is dual-rated and covers both standard families. Strip length 14 mm, torque to 3.5 N·m. The toggle gives local switching, and the trip indicator shows a clear red/green flag when it's tripped — no guessing from across the panel. Earth-leakage protection is handled by a separate block (Vigi iC60), not integrated — so if you need RCD functionality, plan for the add-on module alongside this breaker on the rail.","metaTitle":"Schneider Electric A9F07450 Acti9 iC60H MCB, 50 A C-Curve 4P","metaDescription":"Schneider Electric A9F07450 Acti9 iC60H miniature circuit breaker, 50 A rated, C-curve, 4 poles, 42 kA breaking capacity.
