Product details

The A9P54640 is a Schneider Electric Acti9 iC40N miniature circuit-breaker (MCB) rated at 40 A, 1P+N, with a C-curve trip characteristic. It is a thermal-magnetic device designed for distribution in residential and light commercial AC networks at 50/60 Hz.

Breaking capacity is dual-rated: 10 kA Icu at 230 V AC per IEC 60947-2, and 6000 A Icn at 230 V AC per IEC 60898-1. The higher Icu figure applies when the MCB is used as a distribution breaker per the industrial standard; the Icn figure is for household-type installations. Both standards are listed on the nameplate.

Neutral is on the left. IP20 rated; IP40 in a modular enclosure.
