The MGN02263 is a Schneider Electric Acti9 D02 fuse-switch disconnector — a 2-pole, 63 A unit built for isolating and protecting branch circuits in distribution panels. Rated operational voltage covers 230...400 V AC 50/60 Hz and 110 V DC, with an insulation voltage of 400 V and impulse withstand of 6 kV.
The 63 A rated current and AC-22A utilisation category (per IEC 60947-3) mean this disconnector is rated for switching mixed resistive and inductive loads, including motor circuits with moderate inrush — not just isolating under no-load. The DC-22B rating extends that to DC circuits at 110 V, covering common control-power and battery-backed bus applications. The 6 kV impulse withstand (Uimp) gives it coordination headroom in panels with upstream surge arrestors or high-fault-capacity breakers. Screw-clamp terminals accept 1.5...35 mm² rigid or 1.5...25 mm² flexible conductors, with a tightening torque of 3 N.m and a 14 mm strip length. The 72 mm width (9 mm pitches × 6) fits standard DIN-rail spacing — two of these side-by-side occupy the same footprint as a 4-module MCB.
