Product details

The Schneider Electric A9N18346 is a 100 A rated miniature circuit breaker from the Acti9 C120 series, 2-pole, B-curve, with a 10 kA Icn breaking capacity at 400 V AC.

Rated 10 kA Icn at 400 V AC per EN/IEC 60898-1, and 6 kA Icu at 440 V AC per EN/IEC 60947-2. It also carries 10 kA Icu at 220-240 V and 380-415 V AC under the industrial standard. Dual-rated to both the household (60898-1) and industrial (60947-2) standards, so it qualifies for distribution boards and industrial panel applications alike.

Tunnel terminals accept 1-50 mm² rigid or 1.5-35 mm² flexible, with a 3.5 N·m tightening torque and 15 mm strip length. Neutral position is left; toggle control with ON/OFF local indication.
