Product details

EasyPact NW drawout — 2500 A, 66 kA at 440 V

The Schneider Electric ENW24154 is an EasyPact NW 4-pole drawout circuit breaker rated for 2500 A at 40 °C, with a breaking capacity of 66 kA Icu at 220...440 V AC and 50 kA Icu at 690 V AC, all per IEC 60947-2. The drawout mounting lets you rack the breaker out for maintenance or replacement without pulling the bus bars, which saves hours of downtime on a live panel.

The 1000 V rated insulation voltage (Ui) and 690 V operational voltage (Ue) cover common low-voltage distribution voltages up to 690 V line-to-line.

Integration into the switchboard

Drawout mounting on rails — the breaker slides into a cradle with rear horizontal or vertical connections. The 4-pole configuration (4P 4d) with neutral on the left means it can be set for 3D (no neutral protection), 3D + N/2 (half-rated neutral), or 4D (full neutral protection). Connection pitch is 115 mm without a spreader. The IP40 enclosure protection keeps fingers and tools out but is not sealed against water — install in a dry indoor switchboard. Dimensions: 556 mm wide, 439 mm high, 395 mm deep — plan the cubicle depth accordingly.

Frequently asked questions

What is the breaking capacity of ENW24154?

66 kA Icu at 220...440 V AC and 50 kA Icu at 690 V AC, both per IEC 60947-2. The service breaking capacity Ics is 65 kA at 220...440 V and 50 kA at 690 V.

How do I set the neutral protection on this breaker?

The 4-pole breaker allows three settings: 3D (no neutral protection), 3D + N/2 (neutral protection at half the rated current), or 4D (full neutral protection). The neutral pole is on the left side.
