The Schneider Electric MGP2503NAX is a PowerPact 4 switch disconnector rated for 250 A at 415 V AC, 50/60 Hz, in a 3-pole configuration. It carries AC-22A, AC-23A, DC-22A, and DC-23A utilisation categories — meaning it handles mixed resistive and motor loads, plus the higher switching stresses of motor disconnection. The 250 A rating ties it to 250 A panelboard feeders and 400/630 A panelboard mains. This is a dedicated isolation device — the contact position indicator and suitability-for-isolation marking per BS EN 60947-3 confirm it provides visible-break disconnection for safe maintenance access. The 8 kV rated impulse withstand voltage (Uimp) and pollution degree 3 rating (EN/IEC 60664-1) suit it for industrial environments where transient overvoltages and conductive contamination are present.
The MGP2503NAX is classified as Obsolete per the manufacturer's lifecycle record. The obsolete status means this is a last-time-buy or surplus-channel part; plan for a cross-reference evaluation if the line needs long-term support.
The toggle control provides local manual operation. IP40 enclosure protection keeps out tools and small solids but not moisture; install in a dry, indoor panel. IK07 impact resistance handles incidental mechanical shock during panel servicing. Rated short-time withstand current (Icw) is 3500 A for 1 s or 3 s, and 1350 A for 20 s — this defines the fault-withstand capability for coordination with upstream protective devices. The short-circuit making capacity (Icm) is 4.9 kA peak. Electrical durability is 15,000 cycles at 440 V at rated current, halving to 7,500 cycles at 2× In; mechanical durability is 20,000 cycles.
