It's built for distribution panels where you need a visible-break isolation point that's also rated for switching motor or resistive loads. The 50 A thermal current (Ith) at 40 °C sets the continuous-carry baseline; the AC-23A rating means it can handle occasional motor switching, not just passive loads. That 1.28 kA short-circuit making capacity (Icm) on its own jumps to 150 kA when paired with an upstream breaker — so it's designed to coordinate in a selective chain, not stand alone in a high-fault location. The 108 mm width and 137 mm height fit a standard distribution board footprint; the 27 mm connection pitch lines up with busbar systems. Terminals accept crimp lugs from 2.5 mm² up to 120 mm² (copper or aluminium), or flexible cable up to 95 mm². That range covers most panel feeds from subfeed to main isolator sizes. Toggle control on the front gives a clear mechanical contact-position indicator — no guessing whether it's open or closed. Certified to EN/IEC 60947-1 and EN/IEC 60947-3 — the switch-disconnector standard. IP40 front-of-panel protection keeps tools and fingers out; IK07 impact resistance handles accidental knocks in a live panel. Class II double insulation — no earth connection required on the enclosure. ## Durability and duty cycles Electrical durability depends on load: at 440 V AC, 50/60 Hz, you get 20,000 cycles at half rated current (AC-22A or AC-23A), dropping to 10,000 cycles at full rated current. At 690 V AC, the same pattern yields 10,000 cycles at half current and 5,000 at full current (AC-22A). For AC-23A at 690 V, it's 6,000 cycles at half current and 3,000 at full. That's typical for a compact switch-disconnector — it's not a contactor rated for millions of operations, but it's built for occasional switching and isolation duty in a distribution board. ## Thermal and short-time ratings Short-time withstand current (Icw) is 900 A for 1 second or 3 seconds, and 200 A for 20 seconds — that's the fault current the switch can hold closed for coordination without welding or damage. The 8 kV rated impulse withstand voltage (Uimp) covers typical distribution transient surges.","metaTitle":"Schneider Electric C114050BS ComPacT NSXm 50NA Switch Discon","metaDescription":"Schneider Electric C114050BS ComPacT NSXm 50NA switch disconnector, 4 poles, 50 A rated operational current, 690 V AC.
