Product details

What this MCB does for your panel

The Schneider Electric A9N21542 is a 1 A, curve C, 1P+N miniature circuit breaker from the Clario iDPN family, rated to break 4500 A at 230 V AC per EN/IEC 60898-1.

DIN-rail fit and panel integration

Clip-on mounting to standard DIN rail (EN 60715) — 18 mm width per pole, so this 1P+N unit occupies 2 modules (36 mm). Depth of 78 mm leaves clearance behind most enclosure gland plates. Neutral is on the left, which matters when laying out busbar feeders in a multi-row panel.

IP20 finger-safe terminals. Suitability for isolation marked yes — you can safely use this as a local disconnect where lockout/tagout procedures require visible break indication.
