Schneider Electric 33372 ComPacT NS630b 150kA 3P Basic Circuit Breaker Body - Withdrawable Electrically Operated
630A Frame | 3P | 150kA | Requires Separate MicroLogic Unit
The Schneider Electric 33372 is a ComPacT NS630b molded case circuit breaker rated at 630A with 3-pole configuration and 150kA breaking capacity. This basic circuit breaker frame (requires separate MicroLogic control unit) features an ultimate short-circuit breaking capacity (Icu) of 150kA at 415VAC and 150kA at 220/240VAC, making it suitable for high-fault-current installations. Designed as a withdrawable (chassis-mounted), electrically operated with motor mechanism 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 NS630b 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 33372 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.
