That 1000 A figure is the thermal rating (In), not a short-time or instantaneous pickup; it governs the main bus or feeder it protects. Breaking capacity is 50 kA Icu at 220…440 V AC and 42 kA Icu at 690 V AC, both per IEC 60947-2. The Icu (ultimate breaking capacity) means the breaker can safely interrupt one fault at that level and still be functional afterward — it does not guarantee further service without inspection. Rated operational voltage (Ue) is 690 V AC, and rated insulation voltage (Ui) is 1000 V AC — the latter tells you the internal creepage and clearance are designed for a 1000 V system, even though the breaker is applied at 690 V. That headroom matters for installations where the system voltage may rise or where the breaker sits in a higher-voltage switchgear lineup. ## Deployment context and physical integration This is a fixed-mount breaker on a base plate, not a draw-out or plug-in unit. Dimensions are 537 mm wide × 352 mm high × 297 mm deep — a substantial footprint that needs a dedicated compartment in the switchgear lineup, not a DIN-rail clip. That means it can serve as a disconnecting means for a feeder, satisfying the lockout/tagout requirement without a separate disconnect switch. Designed and tested to IEC 60947-2, the international standard for low-voltage circuit breakers. This covers the breaking capacity ratings, service duty, and isolation suitability listed above. The pollution degree 4 rating per IEC 60664-1 is an additional environmental classification that goes beyond the base standard.","metaTitle":"Schneider Electric ENW24126 EasyPact NW Circuit Breaker, 100","metaDescription":"Schneider Electric ENW24126 EasyPact NW circuit breaker, 1000 A rated current at 40 °C, 50 kA Icu at 440 V AC.
