MCCB | NSX400F LV432676 (Schneider)

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 36kA rms at 415VAC 50/60Hz. The operational voltage is 690VAC 50/60Hz. This product embeds an electronic Micrologic 2.3 trip unit, with 400A rating. Micrologic 2.3 trip unit provides adjustable long time and short time protections, and a fixed instantaneous protection. This 3 poles version (140mm x 255mm x 110mm) 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.
