The Schneider Electric ENW24105 is an EasyPact NW air circuit breaker rated 2000 A at 40 °C, with a breaking capacity of 50 kA Icu at 220...440 V AC 50/60 Hz per IEC 60947-2. The 42 kA Icu at 690 V AC tells you the same breaker handles higher-voltage distribution but with reduced fault-clearing margin. Drawout mounting means the breaker chassis slides into a fixed cradle, so you can rack it out for maintenance without disturbing the bus connections — standard for switchgear where uptime matters.
Deployment context
This breaker is designed for drawout mounting on a rail, typical in low-voltage switchgear lineups where the breaker must be removable for service without de-energizing the bus. IP40 protection means it is suited for indoor electrical rooms — not washdown environments. The rear connection position with a 115 mm pitch without spreader matches standard bus-bar takeoffs in switchgear cubicles.
Certified to IEC 60947-2 for low-voltage switchgear and controlgear. Pollution degree 4 per IEC 60664-1 — the highest severity, meaning it withstands conductive pollution (e.g., dust, moisture) in industrial environments. Rated insulation voltage 1000 V AC, impulse withstand 12 kV.
