The C063S4WM is a Schneider Electric ComPacT NS new generation switch disconnector basic frame, type NA, four-pole, withdrawable, manually operated, and rated 630 A in AC-23A duty across the full 220–690 V AC range.
Ratings That Drive the Fit
The headline number is 630 A conventional free-air thermal current (Ith) at 60 °C and the same 630 A across every AC-23A voltage point from 220 V up to 690 V — no derating needed for higher line voltages in that duty class. Short-time withstand (Icw) is 25 kA for 0.5 s, and the making capacity (Icm) hits 52 kA at 690 V, which tells you this frame can close into a fault and hold through a downstream short without welding contacts.
The frame is withdrawable (drawout), so the switching element can be racked out for inspection or replacement without disturbing the main bus connections. Dimensions: 327 mm wide, 280 mm high, 147 mm deep. Front connections both top and bottom.
