The Schneider Electric DOMF01216 is a Domae miniature circuit breaker (MCB) with a 16 A rated current, C tripping curve, and 2 poles.
The C curve (magnetic tripping limit 5...10 x In) means the breaker tolerates moderate inrush currents — typical for lighting banks, small transformers, and motorized loads — without nuisance tripping. The 6000 A breaking capacity (Icn) is the maximum fault current it can safely interrupt at 230 V AC; that covers most domestic and light commercial service entrances where the prospective short-circuit current stays under 6 kA. The thermal-magnetic trip unit combines a bimetal strip for overload protection and a solenoid for short-circuit response. The 2-pole version (2P) switches both phase and neutral, with the neutral on the left side of the unit. Rated operational voltage is 230 V AC at 50/60 Hz, which is the standard single-phase supply in many regions. The IP20 rating on the body (IP40 in a modular enclosure) means it is protected against solid objects larger than 12 mm but not against water ingress — suitable for indoor distribution boards only.
The 36 mm width (4 x 9 mm pitches) occupies two standard module spaces. Tunnel-type terminals accept 1...25 mm² rigid or 1...16 mm² flexible cable; tighten to 2 N·m. The 18 mm connection pitch between phases is standard for comb busbar systems — the unit is listed as compatible with comb busbars and distribution blocks.
