The Schneider Electric A9N19802 is an Acti9 C120H miniature circuit breaker (MCB) — 3 poles, 63 A rated current at 30 °C, C-curve trip characteristic, and a 10 kA breaking capacity at 400 V AC per IEC 60898-1 and GB/T 10963.1. It clips onto a DIN rail for panel mounting and uses tunnel-type terminals accepting 1–50 mm² rigid or 1.5–35 mm² flexible conductors.
This order code is marked obsolete by the manufacturer. There is no official successor listed in the record.
The C curve (magnetic trip at 5–10 × In, i.e. 315–630 A) suits inductive loads like small motors, transformers, and lighting banks where inrush is moderate. Thermal-magnetic trip technology combines a bimetal strip for overload protection and a solenoid for short-circuit response. The 10,000 electrical / 20,000 mechanical cycle ratings give a service life consistent with panelboard duty — not a frequent-switching application like a motor starter.
Panel integration
Clip-on mounting to a standard 35 mm DIN rail, 9 module pitches wide (9 × 18 mm = 162 mm). Toggle handle with ON/OFF indication. Stripping length 14 mm.
