The Schneider Electric C25W36M220 is a ComPacT NSX250HB2 moulded-case circuit breaker (MCCB) with a MicroLogic 6.2 E-M electronic trip unit, rated 220 A at 65 °C. It is built for motor protection in industrial distribution panels, carrying a 100 kA Icu breaking capacity at 690 V AC 50/60 Hz per IEC 60947-2. The 3-pole unit uses a toggle control and an LCD display for local metering and protection settings.
Motor tripping classes 5, 10, 20, and 30 are selectable, letting you match the trip curve to the motor's starting profile — class 10 for standard induction motors, class 20 or 30 for high-inertia loads like crushers or centrifuges. The 105 mm width and 161 mm height fit standard MCCB panel cutouts.
Deployment context
This MCCB is sized for motor feeder circuits in industrial control panels — typically feeding a motor starter or soft starter for pumps, conveyors, compressors, or fans. The electronic trip unit with ground-fault protection suits applications where earth-leakage detection is required without a separate relay. The LCD display provides real-time energy metering, demand current, and time-stamped event logs, useful for predictive maintenance without an external power meter.
Design complies with EN/IEC 60947-2 for low-voltage switchgear and controlgear. The enclosure carries IK07 impact protection per IEC 62262. Mechanical durability is rated at 20,000 cycles; electrical durability ranges from 5,000 cycles at 690 V In to 20,000 cycles at 440 V In/2.
