The Schneider Electric ENW13220 is a 4-pole EasyPact NW drawout circuit breaker rated 1250 A at 40 °C, built for distribution duty per IEC 60947-2. The 55 kA Ics service rating tells you it can reclose after a fault at that level without maintenance, which matters on a continuous process line where a nuisance trip can't turn into a shift-long outage.
Drawout mounting and panel integration
Drawout mounting means the breaker chassis stays wired to the bus; the moving portion slides out for inspection or swap without disturbing the rear connections. The 70 mm connection pitch without spreader and rear horizontal/vertical connection positions give the panel builder options for busbar routing. Mounts on a rail base plate. IP30 is standard for enclosed switchgear — not for open panel fronts, but fine behind a door.
The 1250 A frame is the continuous current at 40 °C — size your bus and lugs for that, not less. The 66 kA Icu is the ultimate breaking capacity; the 55 kA Ics is the service rating after a fault. The 50 kA Icw for 1 second is the short-time withstand — critical for selective coordination downstream.
