Product details

The Schneider Electric A9N21384 is a DT40N miniature circuit breaker from the ProDis range, rated 6 A with a C curve and 3 poles for AC distribution networks at 50 Hz.

Breaking capacity and dual-standard rating

This breaker carries two breaking-capacity ratings: 6000 A Icn at 400 V AC per EN/IEC 60898-1 and 10 kA Icu at 400–415 V AC per IEC 60947-2.

The tunnel-type terminals accept 0.33–10 mm² flexible or 0.75–16 mm² rigid conductors upstream and downstream. The breaker occupies 6 x 9 mm pitches (54 mm wide) and stands 81 mm high with a depth of 78 mm.

Earth-leakage protection requires a separate block — not integral.
