Schneider Electric NSX630N Compact Circuit Breaker (3-Pole, 630 Amps)
The Schneider Electric NSX630N (MPN: C63N32D630) is a molded case circuit breaker (MCCB) of the popular family of the new generation ComPacT NSX. This 3-pole breaker is very reliable in the most demanding electrical networks, with a 630A continuous current rating and an integrated MicroLogic 2.3 electronic trip unit.
The compact design is optimized for high short-circuit breaking capacity ($50\text{kA}$ at $415\text{ VAC}$) and small installation area. Offers comprehensive protection against overloads and short circuits. Excellent international and marine certifications support the strict build quality, resulting in a valuable global asset for critical power infrastructure.

Applications
- Commercial Building Mains. Protected Segmented Main Low Voltage Power Distribution Networks.
- Industrial Plants & Manufacturing Heavy duty feed protection for production lines and automated conveying systems.
- Marine & Offshore Applications: Dependable protection for shipboard switchboards, auxiliary generator circuits and cargo equipment control systems.
- Data Centers & Infrastructure: High availability main switchboards without zero-compromise coordination and electronic discrimination
- Motor Control Centers (MCC): Optimal upstream feeding branch breaker for large industrial pumps and compressors starters.
Engineer’s Insight:
On a vessel or a tightly enclosed industrial plant floor, ambient temperature is your enemy. The NSX630N is calibrated for a baseline of 40°C. If your engine room or switchboard room regularly sustains temperatures near 50°C, you must calculate thermal de-rating curves. Fortunately, because this unit uses the MicroLogic electronic trip unit instead of standard thermal-magnetic strips, it behaves much more predictably under high ambient heat, drastically reducing annoying nuisance trips caused by environmental temperatures rather than actual overcurrent.
