Schneider Electric C125N3WM ComPacT NS1250 50kA 3P Basic Circuit Breaker Body - Withdrawable Manual
1250A Frame | 3P | 50kA | Requires Separate MicroLogic Unit
Part number C125N3WM identifies the Schneider Electric ComPacT NS1250 MCCB rated at 1250A with 3-pole configuration and 50kA breaking capacity. This basic circuit breaker frame (requires separate MicroLogic control unit) features an ultimate short-circuit breaking capacity (Icu) of 50kA at 415VAC and 85kA at 220/240VAC, making it suitable for high-fault-current installations. Designed as a withdrawable (chassis-mounted), manually operated via toggle handle device, it complies with IEC 60947-2 international standards. Supplied without a trip unit, this frame accepts any compatible MicroLogic control unit (2.0, 5.0, 6.0, or advanced A/E/P variants) for customizable protection configuration. The rated insulation voltage of 1000V and impulse withstand of 8kV ensure reliable dielectric performance. With pollution degree 3 certification for industrial environments and IP40 protection rating, the ComPacT NS1250 is ideal for main distribution, sub-distribution, and motor feeder protection in commercial and industrial facilities. Compact dimensions of 327 x 210 x 147 mm allow efficient switchboard integration. Part of the Schneider Electric ComPacT NS new generation range (630A to 3200A), this IEC-rated breaker provides class II front-face protection and positive contact indication for safe isolation. The C125N3WM features Green Premium ecolabel certification, confirming environmental compliance with RoHS and REACh directives. Suitable for temperatures from -25°C to +70°C with derating provisions, it integrates seamlessly with Schneider Electric's EcoStruxure power monitoring architecture.
