The Schneider Electric C10R36M050 is a ComPacT NSX circuit breaker from the NSX100R frame, fitted with a MicroLogic 6.2 E-M electronic trip unit and rated for motor protection at 50 A at 65 °C.
Above that ambient, derating applies per the manufacturer's curve. The MicroLogic 6.2 E-M provides L (long-time overload), So (short-time short-circuit), I (instantaneous), and G (ground fault) protection, with selectable motor tripping classes 5, 10, 20, and 30. Class 10 is standard for general-purpose motor starting; class 20 or 30 accommodates high-inertia loads like fans or centrifuges that take longer to accelerate. At 690 V AC the rating drops to 45 kA Icu — still substantial for a 690 V motor feeder. The breaker carries a utilisation category A (non-selectively coordinated for short-circuit), so it is suited for standalone motor protection or as part of a cascaded system where the upstream device handles selectivity.
The 105 mm width and 161 mm height fit standard ComPacT NSX cutouts; depth is 86 mm. Five accessory slots are available for auxiliary contacts, shunt trips, or communication modules. The LCD display on the MicroLogic 6.2 E-M shows energy metering, demand values, and event logs — useful for commissioning and troubleshooting.
