The ENW24123 is a 3200 A air circuit breaker from the EasyPact NW range, designed for distribution duty in low-voltage switchgear. The 42 kA Icu at 690 V AC covers higher-voltage installations. Rated service breaking capacity Ics matches the Icu values, meaning after clearing a fault at those levels the breaker remains serviceable, not just safe. The drawout mounting (rail-supported) lets you rack the breaker out for maintenance without disturbing the busbars — a standard feature on large air breakers for panel builders.
Deployment context
At 556 mm wide, 439 mm high, and 395 mm deep, this breaker fits into a dedicated drawout cradle in a low-voltage switchboard. The rear connection position (vertical or horizontal) and 115 mm connection pitch without spreader dictate busbar drilling and cable landing layout. The push-button control and contact position indicator give clear local status without opening the door.
Certified to IEC 60947-2 for low-voltage switchgear and controlgear. Suitability for isolation is confirmed, so it can be used as a disconnecting means. The 4-pole version (4P 4d) allows full neutral protection with selectable settings: without protection (3D), 0.5 x Ir (3D + N/2), or 1 x Ir (4D).
