The Schneider Electric ENW24271 is a switch disconnector in the EasyPact NW range, rated for 1250 A in AC-23A duty at 690 V AC. Four poles, neutral on the right, fixed mounting on a base plate. The rear connection pitch is 115 mm without a spreader.
Rated operational current is 1250 A in AC-23A at 690 V. That's the motor-switching current, not the resistive-heating rating — if you're feeding a bank of heaters at unity power factor, the part will handle more, but for motor loads this is your hard ceiling. Continuous duty rated, so no derating for sustained on-time. Short-time withstand (Icw) is 50 kA for 1 second, or 25 kA for 3 seconds. That tells you the disconnector can ride through a fault long enough for an upstream breaker to clear — critical for selective coordination in a distribution board. Short-circuit making capacity (Icm) is 105 kA peak, meaning it can close onto an existing fault without welding contacts. Impulse withstand voltage is 12 kV, and pollution degree 4 per IEC 60664-1 — that's the heavy-industrial rating for conductive dust or condensation inside the enclosure. If your panel lives in a cement plant or a paper mill, that matters more than the IP rating. Electrical durability at 440 V AC is 6,000 cycles; at 690 V it drops to 4,000 cycles. That's typical for a high-current AC-23A switch — plan your maintenance intervals around the 690 V figure if that's your line voltage.
