For a 690 V system the Icu drops to 50 kA, still substantial for most industrial distribution. The drawout mounting means the breaker chassis stays wired to the bus while the moving portion slides out for maintenance or replacement — common in switchgear where downtime must be minutes, not hours. IP40 keeps tools and fingers out but is not washdown-rated; this lives in a clean indoor switchboard. ## Integration and deployment Mounts on a rail in a drawout configuration — the fixed portion bolts to the switchgear frame, the moving portion slides in on guided rails. Rear connection with a horizontal or vertical orientation. The neutral is on the right. Connection pitch is 115 mm without a spreader. Dimensions: 556 mm wide × 439 mm high × 395 mm deep. The contact position indicator gives a visible open/closed state without opening the door. Designed to IEC 60947-2 for low-voltage switchgear and controlgear. Suitability for isolation is confirmed — the breaker provides visible isolation when open. Rated insulation voltage 1000 V AC, impulse withstand 12 kV. Short-time withstand current 65 kA for 1 s at 440 V — key for selective coordination studies. Electrical durability: 5000 cycles at 440 V without maintenance; mechanical durability 20000 cycles with maintenance. Maximum breaking time 25 ms; maximum closing response 70 ms.","metaTitle":"Schneider Electric ENW24251 EasyPact NW Circuit Breaker, 320","metaDescription":"Schneider Electric ENW24251 EasyPact NW air circuit breaker, 3200 A rated current, 66 kA breaking capacity at 440 V AC, IEC 60947-2, drawout mount, IP40.
