Description
About the NSX400NA DC PV
About the NSX400NA DC PV
The Schneider Electric C404400D1S is a 4-pole ComPacT NSX400NA DC PV switch-disconnector rated 320 A (DC-22A) at 1000 V DC, built for photovoltaic DC distribution. It provides manual load-break isolation with a 6 kA short-time withstand and short-circuit making capacity, sized for the DC side of a solar array combiner or inverter input.
Certifications & Standards
- EN/IEC 60947-1
- EN/IEC 60947-3
Selection Notes
The C404400D1S is a switch-disconnector, not a circuit breaker, so it provides manual isolation of a PV DC string or inverter input but no overcurrent trip of its own; upstream fuses or a DC breaker still handle fault clearing. The 6 kA Icw/Icm rating and 1000 V DC insulation level size it for utility- and commercial-scale PV combiner boxes rather than low-voltage 600 V DC residential strings, where a lower-voltage ComPacT NSX switch-disconnector would be the better fit.
