The C63W32M500 is a Schneider Electric ComPacT NSX630HB2 moulded-case circuit breaker, 3-pole, rated 500 A at 65 °C. It carries a MicroLogic 2.3 M electronic trip unit — that M suffix means it's configured for motor protection, with adjustable overload (L), short-time (So), and instantaneous (I) protection curves. The 100 kA Icu at 690 V AC (EN/IEC 60947-2) gives you headroom on high-fault industrial networks; you're not chasing coordination studies when the transformer is stiff.
The MicroLogic 2.3 M offers three motor tripping classes — 5, 10, and 20 — so you match the thermal model to your motor's startup profile (class 20 for high-inertia loads like centrifuges, class 5 for short acceleration).
Front connections top and bottom — standard for panel wiring. IP40 enclosure protection (IK07 impact) means it's fine inside a clean industrial panel; not for washdown zones.
