The Schneider Electric A9N60712 is an Acti9 C120 miniature circuit-breaker (MCB) rated 100 A at 40 °C with a C-curve trip characteristic, 2 poles protected, and a breaking capacity of 5 kA Icu at 230...400 V AC 50/60 Hz per EN/IEC 60947-2.
The C-curve (magnetic trip at 8 x In ±20 %) means it tolerates moderate inrush, typical for motor-starter or transformer-fed circuits where the start surge is higher than a resistive load but not extreme.
Integration and approvals
Mounts via clip-on onto a 35 mm symmetrical DIN rail. The tunnel-type terminals accept 1...50 mm² rigid or 1.5...35 mm² flexible cable; strip 15 mm and torque to 3.5 N.m. IP20 finger protection. The toggle provides ON/OFF indication and a padlock provision for lockout/tagout. Earth-leakage protection requires a separate block — not integrated.
