The Schneider Electric DOM11348SNI is a Domae-series miniature circuit breaker (MCB) — 3 poles, 10 A rated current, C-curve trip characteristic, rated operational voltage 380...415 V AC at 50 Hz. Breaking capacity is 4.5 kA at 400 V AC per IEC 60898-1, which means it safely clears a fault up to that level on a 400 V distribution board without upstream fuse coordination being mandatory. Clip-on mounting to DIN rail; the 6 module pitches (9 mm each) fit a standard 54 mm width on the rail.
The 380...415 V AC rating covers the standard three-phase low-voltage network range. Toggle control, grey housing, comb-busbar compatible.
