The Schneider Electric ENW13211 is a 3-pole EasyPact NW circuit breaker rated 1000 A at 40 °C, built for distribution duty in AC networks at 50/60 Hz. For selective coordination with downstream gear, the short-time withstand (Icw) is 50 kA for 1 second, and the making capacity (Icm) is 75 kA — both at 220...440 V AC. That's a Category B breaker (utilisation category B), so it's designed for selectivity in distribution, not just cable protection.
Fixed mount on a rail base plate — no draw-out cradle here. Connection is rear, horizontal or vertical, with a 70 mm pitch without spreader. The footprint is 276 mm wide by 301 mm tall by 196 mm deep.
Durability and environmental range
Mechanical endurance: 20,000 cycles with maintenance, 10,000 without. Electrical endurance: 5,000 cycles at 440 V AC without maintenance. Max breaking time is 35 ms, max closing time 70 ms. The contact position indicator is fitted — a green/red flag visible on the front so you can confirm open/closed without metering.
