The Schneider Electric C113050BS is a ComPacT NSXm 50NA three-pole switch disconnector rated 50 A at 690 V AC. It's the part you grab when you need a manual disconnect that doubles as an isolation point — the toggle gives positive break indication, and it's certified for isolation per EN/IEC 60947-3. Mounts on a 35 mm DIN rail or a backplate, so it fits standard enclosures without special bracketry.
What the ratings mean for fit
The 50 A rating in AC-22A and AC-23A utilisation categories means it handles both resistive and moderately inductive loads — think distribution panels, motor disconnects on smaller drives, or heater banks. The 690 V AC rated operational voltage covers 400 V and 480 V systems with headroom. Short-time withstand (Icw) of 900 A for 1 s tells you it can ride through a fault long enough for an upstream breaker to clear, which matters for selectivity coordination. The making capacity of 1.28 kA alone jumps to 150 kA when paired with an upstream circuit breaker — that's the real-world number for panel design.
Integration and mounting
Fixed mounting on a 35 mm DIN rail or backplate, with a 27 mm connection pitch. Terminals accept crimp lugs from 2.5 to 120 mm² (copper or aluminium) or busbar connectors — so it's ready for both cable and busbar distribution in a panel. IP40 front face means it's fine inside a closed cabinet; no washdown rating, so keep it out of wet areas. The contact position indicator and visible break (toggle) give a clear visual check during lockout/tagout.
