Product details

What this 16 A Curve C breaker is for

The Schneider Electric A9N21597 is an iDPN N miniature circuit breaker from the Clario range, rated 16 A with a C trip curve and 3 protected poles plus switched neutral. The thermal-magnetic trip handles overloads and short circuits up to 6000 A Icn at 400 V AC, per EN/IEC 60898-1 — that's the standard for household and similar fixed-wiring protection.

Mounting and wiring at the panel

Clip-on mounting to DIN rail, 6 modules of 9 mm pitch (54 mm wide). Tunnel terminals accept 0.33 to 10 mm² flexible or 0.75 to 16 mm² rigid upstream and downstream. The neutral is on the left, and the toggle gives ON/OFF indication. IP20 rated — fine inside an enclosure, not for wet locations.

Frequently asked questions
