It carries a 66 kA Icu at 220...440 V AC and 50 kA Icu at 690 V AC, both per IEC 60947-2, so it clears high fault currents without upstream coordination issues. The 4-pole design with left-side neutral and rear vertical/horizontal connections suits main or tie-breaker positions in low-voltage switchgear. That 65 kA Ics / 66 kA Icu ratio (98 %) is high, typical of Category B breakers that are expected to remain in service after a fault. The 690 V operational voltage (Ue) and 1000 V insulation voltage (Ui) confirm it handles 690 V line-to-line systems common in heavy industrial plants. Fixed mount on a base plate — no DIN rail, so panel cutouts and bolt patterns need to match the 537 mm width, 352 mm height, and 297 mm depth. Rear connection with a 115 mm connection pitch without spreader means busbar or cable terminations must follow that spacing. IP40 enclosure protection keeps out tools and fingers but not water; install inside a switchboard or enclosure rated for the environment. Pollution degree 4 per IEC 60664-1 means the breaker is designed for continuous conductive contamination (dust, condensation) — typical for unsealed industrial switchgear rooms. Certified to IEC 60947-2 for low-voltage switchgear and controlgear. Isolation suitable per that standard — the breaker provides visible isolation when open. Pollution degree 4, ambient operation from -5 to 60 °C, storage from -40 to 85 °C. The 4 protected poles (4P 4d) with selectable neutral protection (no protection, 0.5× Ir, or 1× Ir) cover solidly-grounded and impedance-grounded systems.","metaTitle":"Schneider Electric ENW24157 EasyPact NW Circuit Breaker, 800","metaDescription":"Schneider Electric ENW24157 EasyPact NW circuit breaker, 800 A rated current at 40 °C, 66 kA Icu at 440 V AC, IEC 60947-2, 4 poles, IP40, fixed mount, current lifecycle stage, avai","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Air Circuit Breakers"],"specifications":{"Depth":"297 mm","Range":"EasyPact","Width":"537 mm","Height":"352 mm","Standards":"IEC 60947-2","Control type":"Push-button","Network type":"AC","Mounting mode":"Fixed","lifecycle_stage":"current","Connection pitch":"115 mm without spreader","Mounting support":"Base plate","Neutral position":"Left","Pollution degree":"4 conforming to IEC 60664-1","Range of product":"EasyPact NW","Breaking capacity":"66 kA Icu at 220...440 V AC 50/60 Hz conforming to IEC 60947-2 50 kA Icu at 690 V AC 50/60 Hz conforming to IEC 60947-2","Device short name":"ENW08H","Network frequency":"50/60 Hz","Poles description":"4P","Device application":"Distribution","[In] rated current":"800 A at 40 °C","Connection position":"Vertical Horizontal","Utilisation category":"Category B","Electrical durability":"Category B: 6000 cycles 440 V AC 50/60 Hz without maintenance conforming to IEC 60947-2 Category B: 4000 cycles 690 V AC 50/60 Hz without maintenance conforming to IEC 60947-2","Maximum breaking time":"25 ms","Mechanical durability":"20000 cycles (with maintenance) conforming to IEC 60947-2 10000 cycles (without maintenance) conforming to IEC 60947-2","Breaking capacity code":"H","Location of connection":"Rear","IP degree of protection":"IP40","Circuit breaker CT rating":"800 A","Product or component type":"Circuit breaker","Suitability for isolation":"Yes conforming to IEC 60947-2","Contact position indicator":"Yes","Neutral protection setting":"Without protection (3D) 0.5 x Ir (3D + N/2) 1 x Ir (4D)","Protected poles description":"4P 4d","Maximum closing response time":"70 ms","[Ui] rated insulation voltage":"1000 V AC 50/60 Hz conforming to IEC 60947-2","[Ue] rated operational voltage":"690 V AC 50/60 Hz conforming to IEC 60947-2","Ambient air temperature for storage":"-40...85 °C without control unit -25...85 °C with control unit","Ambient air temperature for operation":"-5...60 °C","[Ics] rated service breaking capacity":"65 kA (Ics) at 220...440 V AC 50/60 Hz conforming to IEC 60947-2 50 kA (Ics) at 690 V AC 50/60 Hz conforming to IEC 60947-2","[Uimp] rated impulse withstand voltage":"12 kV conforming to IEC 60947-2","[Icw] rated short-time withstand current":"65 kA (1 s) at 220...440 V AC 50/60 Hz conforming to IEC 60947-2 50 kA (1 s) at 690 V AC 50/60 Hz conforming to IEC 60947-2 36 kA (3 s) at 440/690 V AC 50/60 Hz conforming to IEC 60947-2","[Icm] rated short-circuit making capacity":"143 kA (Icm) at 220...440 V AC 50/60 Hz conforming to IEC 60947-2 105 kA (Icm) at 690 V AC 50/60 Hz conforming to IEC 60947-2"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/cc2a4fdb6211521562e5d0021d440445.pdf","sourceUrl":"https://www.se.com/in/en/product/ENW24157/circuit-breaker-frame-adapt-easypact-nw-4-poles-800a-h-fixed/","alternativesUrl":"https://aoctrl.com/api/mcp/products/ENW24157/alternatives.json"},"ai":{"faq":[{"question":"What is the breaking capacity of the ENW24157?","answer":"The ENW24157 has a 66 kA Icu at 220...440 V AC and 50 kA Icu at 690 V AC, both per IEC 60947-2.
