The C063S3WM is a basic frame switch disconnector from the Schneider Electric ComPacT NS new generation line. It's a 3-pole, manually operated unit rated 630 A in AC-23A duty across the full voltage range (220 V to 690 V AC), making it a straight choice for motor switching and mixed-load disconnection in distribution panels. The withdrawable chassis means you can rack it out for safe maintenance without disturbing the power wiring — a real time-saver when you're swapping a unit on a live bus.
Rated operational current holds at 630 A across all AC-23A voltages (220/240 V through 660/690 V), so you don't have to derate for higher supply voltages — the full 630 A is available at 690 V. The conventional free-air thermal current (Ith) is also 630 A at 60 °C, which matches the AC-23A number; no thermal bottleneck. Short-time withstand current (Icw) is 25 kA for 0.5 s, giving you headroom for selective coordination with upstream breakers. The 8 kV impulse withstand voltage (Uimp) confirms it's rated for installation in standard 400 V-class distribution with typical surge exposure. The unit carries an IP40 enclosure rating and IK07 impact protection, so it's suited for indoor panel mounting where occasional tool contact or light mechanical shock is expected — not for washdown environments.
Integration notes
Dimensions: 327 mm wide, 210 mm high, 147 mm deep. Withdrawable mounting means the chassis slides into a fixed cradle; plan for the extra depth needed for racking clearance behind the door.
