The C063N32EFM is a ComPacT NS new generation 3-pole fixed-mount MCCB rated 630 A at 50 °C. Breaking capacity: 85 kA Icu at 240 V, 50 kA at 415 V, 40 kA at 525 V, 30 kA at 690 V. The MicroLogic 2.0 E trip unit provides L (long-time overload) and I (instantaneous short-circuit) protection. No ground-fault element — if your circuit requires earth-leakage protection, you'll need an external relay or a different trip unit. The electronic trip gives you thermal memory (20 min) for repeated overloads, which a thermal-magnetic breaker lacks — that matters for motor-starting or welding loads where successive inrush events can overheat the cable before the trip curve resets.
Fixed-mount on a backplate. The 210 mm width, 327 mm height, 147 mm depth and 70 mm connection pitch are the envelope you need to reserve in the panel layout. Front-connect top and bottom — no rear-access required, which simplifies the gland plate and busbar routing.
The product carries EN/IEC 60947-2 certification for low-voltage switchgear.
