The DOMF01363 is a 3-pole miniature circuit breaker from the Schneider Electric Domae range, rated 63 A with a C curve and an Icn breaking capacity of 6000 A per IEC 60898-1. It clips onto a DIN rail and occupies 6 modules of 9 mm pitch (54 mm total width). The thermal-magnetic trip unit provides overload and short-circuit protection for AC circuits up to 400 V at 50/60 Hz.
The C curve means the magnetic trip operates at 5 to 10 times the rated current (315 to 630 A), which suits loads with moderate inrush — think lighting banks, small transformers, or motor circuits where the start-up surge is higher than a B curve would tolerate but not as high as a D curve demands. The 6000 A Icn (rated short-circuit breaking capacity) is the maximum fault current the breaker can safely interrupt at 400 V AC; for installations with higher prospective fault current, a breaker with a higher Icn (e.g. 10 kA or 25 kA) would be needed.
Tunnel terminals accept 1 to 35 mm² rigid or 1 to 25 mm² flexible conductors; tighten to 3.5 N.m. Strip 14 mm of insulation. The IP20 rating on the body (IP40 in a modular enclosure) means it is protected against solid objects larger than 12 mm (fingers) but not against moisture — install inside a panel. Comb busbar compatible for multi-pole distribution.
