This is a 4 poles basic switch for ComPacT NSX400H. ComPacT NSX is designed to optimize space and breaking capacity for all standard and special applications. This basic switch is supplied without trip unit and is compatible with all types of trip units that must be ordered separately. The breaking capacity Icu is 70 kA at 415 VAC 50/60 Hz. The operating voltage is 690 VAC 50/60 Hz (limited to 440 VAC 50/60 Hz if residual current protection is present). It can be equipped with a wide range of optional features and accessories. The dimensions are 185 mm x 255 mm x 110 mm. It ensures compliance with international standards (IEC 60947), CCC, EAC and marine specifications. ComPacT NSX400H is part of Schneider Electric's EcoStruxure Power architecture.
