The Schneider Electric DOM11336SNI-B is a Domae-series miniature circuit breaker (MCB) rated for 63 A on a single pole, with a C-curve trip characteristic and a breaking capacity of 4.5 kA at 230/400 V AC 50/60 Hz per IEC 60898-1. Clip-on mounting to DIN rail (18 mm width per pole) fits standard panel layouts.
The 4.5 kA breaking capacity at 230/400 V AC means it can safely interrupt a fault current up to that level; in a panel with a higher available fault current (say 10 kA or more), this breaker would not coordinate and you would need a higher-rated device. The C curve (5–10× In magnetic trip) avoids nuisance trips on capacitive or transformer inrush while still protecting against short circuits. The 18 mm width per pole keeps the assembly compact — 18 mm for a 1P breaker on DIN rail.
Integration notes
Mounts via clip-on to standard 35 mm DIN rail. Tunnel-type terminals accept 1–35 mm² rigid or 1–25 mm² flexible copper; tighten to 3.5 N·m. Strip length 14 mm for AC connections. Compatible with comb busbars and distribution blocks for daisy-chaining outgoing circuits.
