The Schneider Electric iDPN circuit breaker, identified by the part number A9N21555, is a single-pole plus neutral (1P+N) device designed for overcurrent protection. This breaker is part of the iDPN N series, a range of compact circuit breakers commonly utilized in residential, commercial, and light industrial electrical distribution systems. Its C curve tripping characteristic makes it suitable for protecting circuits with moderate inductive loads, such as small motors or fluorescent lighting, where inrush currents are expected but should not cause nuisance tripping.
