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.","metaTitle":"Schneider Electric A9N21542 iDPN MCB, 1A Curve C, 1P+N, 4.5k","metaDescription":"Schneider Electric A9N21542 iDPN miniature circuit breaker, 1 A, curve C, 1P+N, 4500 A breaking capacity at 230 V AC, EN/IEC 60898-1.
