The Schneider Electric DOM11345SNI is a Domae-series miniature circuit breaker (MCB) for distribution boards — 1 pole, rated 32 A, C-curve trip characteristic, breaking 4.5 kA at 230 V AC per IEC 60898-1. Clip-on DIN rail mount, toggle control, grey housing. This is the single-pole version protecting one line; the 32 A rating suits general-purpose branch circuits feeding lighting, socket outlets, or small motor loads within the 4.5 kA fault-current ceiling.
This part is obsolete per the manufacturer's lifecycle record.
Clip-on mounting to DIN rail, 2 module pitches (9 mm each = 18 mm wide).
