The Schneider Electric DOMF01350 is a Domae-series miniature circuit breaker (MCB) rated for 50 A on a 3-pole, 400 V AC 50/60 Hz network. Breaking capacity is 6000 A (Icn), which is the standard residential and light-commercial fault level for IEC 60898-1 installations.
Clip-on mount to a DIN rail (35 mm symmetrical rail per IEC 60715). Occupies 6 x 9 mm pitches (54 mm wide), so it takes three standard module widths in a distribution board. Strip length 14 mm, tighten to 3.5 N.m. Connection pitch between phases is 18 mm — compatible with standard comb busbars and distribution blocks.
Environmental and durability
Rated IP20 (finger-safe terminals) and IP40 inside a modular enclosure. Electrical endurance 10,000 cycles, mechanical 20,000 cycles. Overvoltage category III, suitable for fixed-installation downstream of the utility meter.
