The Schneider Electric DOM12251SNI is a Domae-series miniature circuit breaker — 1-pole, 2 A rated current, C-curve trip characteristic, rated 220...240 V AC at 50 Hz. Clips onto DIN rail; toggle control, grey housing.
The 2 A rating on a C-curve means this breaker holds through short-duration inrush up to 5-10x rated current before the magnetic trip operates — typical for lighting banks or small transformer primaries. Single-pole (1P) switches only the phase; the neutral is not switched or protected.
Panel integration
Clip-on mount to DIN rail, 2 x 9 mm module pitches wide. Comb busbar and distribution block compatible. Fits standard distribution boards and sub-distribution enclosures. Toggle control with clear ON/OFF indication.
