3P3T MICROLOGIC 1.3 M 320A NSX400H front

3P3T MICROLOGIC 1.3 M 320A NSX400H

This Compact NSX400H is a complete 3P 3d fixed circuit breaker designed to optimize space and breaking capacity. It is an optimal choice for motor protection applications. The breaking capacity (Icu) is 70kA rms at 415VAC 50/60Hz. The operational voltage is 690VAC 50/60Hz. This product embeds an electronic Micrologic 1.3 M trip unit, with 320A rating. Micrologic 1.3 M trip unit provides an adjustable short time protection 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 NSX400H is part of Schneider Electric EcoStruxure Power architecture.
