Description
About the NSX630F DC
About the NSX630F DC
The C63F4TM600D is a Schneider Electric ComPacT NSX630F DC 4-pole DC moulded case circuit breaker rated 600 A at 40 °C and 750 V DC, with a 36 kA breaking capacity (Icu) across the full DC voltage range. Its TM-DC thermal-magnetic trip unit gives adjustable overload and short-circuit protection without electronic components.
Certifications & Standards
- EN/IEC 60947-2
Selection Notes
The TM-DC trip unit gives adjustable overload protection (Ir 0.7–1×In) and adjustable magnetic short-circuit protection (Ii 2.5–5×In) without electronic components, which keeps the device simple for DC distribution or photovoltaic combiner applications. The 36 kA breaking capacity stays constant from 24 V DC up to 750 V DC because the poles connect in series for the higher-voltage ratings — the series 3-pole connection is what delivers the full 36 kA at 750 V DC. Choose the 600 A rating over the other TM-DC variants in the same frame to match the DC feeder or string combiner current.
