The Schneider Electric C63R36M500 is a ComPacT NSX630R 3-pole moulded-case circuit breaker rated 500 A at 65 °C, fitted with a MicroLogic 6.3 E-M electronic trip unit. The toggle-operated breaker mounts on a backplate, connects front-top and front-bottom, and includes an LCD display for metering and protection settings.
The R-code breaking capacity delivers 200 kA Icu at 220/240 V AC and 380/415 V AC, 80 kA at 500 V AC, and 45 kA at 660/690 V AC. The MicroLogic 6.3 E-M trip unit provides L (long-time), So (short-time short-circuit), I (instantaneous), and G (ground-fault) protection. Motor tripping classes 5, 10, 20, and 30 are selectable, so it matches the thermal curve of a 500 A motor circuit — pump, conveyor, compressor — without nuisance tripping on start-up inrush.
Front-face connections top and bottom — 45 mm connection pitch — so it fits standard panel busbar layouts. Six accessory slots accommodate shunt trips, auxiliary contacts, or communication modules. The LCD display shows demand current, power, energy metering, time-stamped event logs, and protection settings — no separate panel meter needed for motor load monitoring.
