Overview
The A9F86132 is a Schneider Acti9 iC60H miniature circuit breaker rated 32 A with a B-curve trip characteristic and a 42 kA breaking capacity (Icu) per IEC 60947-2, in a 1-pole, 18 mm wide package.
The B-curve (magnetic trip at 4 x In ±20%) is designed for resistive and lighting loads with low inrush; the 42 kA Icu rating provides headroom for high-fault installations without requiring a current-limiting upstream device.
Compared to the A9F87140 (C-curve, 40 A, 8 x In ±20%), the A9F86132's B-curve trips faster on moderate overloads, making it the better choice for lighting and general-purpose circuits; the A9F87140 suits motor or transformer loads with higher inrush.
