Description
Product Name
Circuit breaker ComPacT NSX400F, 36kA at 415VAC, MicroLogic 2.3 trip unit 400A, 3 poles 3d
General Information
This ComPacT NSX400F is a complete 3P 3d fixed circuit breaker designed to optimize space and breaking capacity. It is an optimal choice for all standard and specific applications. The breaking capacity (Icu) is 36 kA rms at 415VAC 50/60Hz. The operational voltage is 690 V AC 50/60 Hz. This product embeds an electronic MicroLogic 2.3 trip unit, with 400 A rating. MicroLogic 2.3 trip unit provides adjustable long time and short time protections, and a fixed instantaneous protection. This 3 poles version (14 cm x 25.5 cm x 11 cm) comes with a variety of optional functions and accessories. It is compliant with international standards (IEC 60947), CCC, EAC and marine specifications. ComPacT NSX400F is part of Schneider Electric EcoStruxure Power architecture.
