The A9N60750 is a Schneider Acti9 C120 miniature circuit breaker with 2 poles, a D-curve, and a switching current rating of 100 A at 400 V AC/DC. It uses a thermal-magnetic trip unit and complies with EN/IEC 60947-2. The 10 kA breaking capacity (Icu) suits distribution panels where high inrush loads — motors, transformers — require the D-curve's 12 x In magnetic trip limit.
