That's a serious short-circuit rating for industrial distribution, sized for high-fault panels downstream of large transformers or near the service entrance. That So curve with the fixed time delay lets you coordinate selectively with downstream breakers — the 2.2 holds for a set time before tripping on a short, so the fault clears closer to the load instead of taking out the whole panel. ## Mounting, wiring, and what fits in the enclosure Front connections top and bottom, with a 35 mm connection pitch that matches standard busbar systems. Five accessory slots let you add shunt trips, auxiliary contacts, or a motor operator without breaking down the breaker. The toggle control is manual — no motor operator included, but one can go in a slot. The 100 kA Icu at 690 V AC is the ultimate breaking capacity; the service breaking capacity (Ics) is typically 50% or 100% of Icu per IEC 60947-2, so verify coordination studies against the Ics value if your design uses the breaker for through-faults.","metaTitle":"Schneider Electric C25W32D160 ComPacT NSX 160A, 100kA at 690","metaDescription":"Schneider Electric C25W32D160 ComPacT NSX circuit breaker. 160A MicroLogic 2.2 electronic trip unit, 100kA Icu at 690V AC.
