Schneider Electric A9F07150 is an Acti9 iC60H miniature circuit-breaker, 1-pole, rated 50 A with a C curve. That 18 mm width means it slots into a crowded panel without eating up rail space — one less thing to re-layout.
The iC60H carries a 42 kA Icu at 12…60 V AC and 30 kA Icu at 100…133 V AC, dropping to 15 kA Icu at 220…240 V AC. For a 50 A MCB on a 230/240 V distribution board, 15 kA Icu gives you headroom above typical domestic and light commercial prospective fault levels. The C curve (magnetic trip at 8 x In ±20 %) means it holds through motor inrush and transformer energization but trips fast on a hard short — a good fit for general distribution and mixed loads.
Snaps onto a DIN rail (mounting support: DIN rail).
