The DOMF01263 is a 2-pole Domae miniature circuit breaker from Schneider Electric, rated 63 A with a C-curve trip characteristic and an Icn breaking capacity of 6000 A per IEC 60898-1.
Clip-on mounting to a standard DIN rail, 36 mm wide (2 module pitches at 18 mm per pole). The tunnel terminals accept 1 to 35 mm² rigid or 1 to 25 mm² flexible copper, with a strip length of 14 mm and a tightening torque of 3.5 N·m — enough to land a 6 AWG or 25 mm² feeder without a lug. Depth of 71.5 mm and height of 81 mm; the neutral is on the left. The 18 mm connection pitch between phases lines up with standard comb busbars — the part is marked as compatible with comb busbar and distribution block systems.
Durability and environment
Rated for 10,000 electrical and 20,000 mechanical cycles. IP20 finger-safe on the front; IP40 when installed in a modular enclosure. Overvoltage category III (distribution level). CE marked, designed to IEC 60898-1.
