It is compatible with or cross-references Chint NXB-63 series accessories (auxiliary contacts, shunt trips, alarm contacts), Chint NXB-125 series for higher current applications. Equivalent / cross-reference designation: Chint NXB-63 C10 3P, ABB S201-D10, Schneider iC60N 10A 3P. Within industrial automation and process-control environments, components of this type are relied upon to keep critical equipment operating safely and efficiently. They are typically specified where uptime, repeatability and a predictable maintenance cycle matter more than upfront cost. Chint parts are widely used across power generation, manufacturing, oil and gas, water and process industries, where engineering teams standardise on proven series to simplify spares planning. When selecting a replacement, confirm the exact model designation and verify that the mechanical and electrical interface matches the unit currently installed. Cross-checking the order code, mounting style and connection type against the existing device helps avoid compatibility issues and unplanned downtime during a maintenance window. Where several variants exist, the suffix often defines voltage, range or firmware, so it should be matched precisely rather than approximated. This item is offered from our active stock of current and discontinued industrial parts. Each listing is verified against the manufacturer designation before shipment so you receive the correct part for your application. Availability and lead time vary by item; our team can confirm the fastest option for your required quantity and provide a formal quotation on request. Common questions: Regarding "What is the breaking capacity of the Chint NXB-63 D10 3P": The breaking capacity is 6kA, suitable for most industrial and commercial applications. Regarding "What is the difference between D10 and C10 trip curves": The D curve has a higher magnetic trip threshold (10-20x In) compared to the C curve (5-10x In), making it suitable for loads with high inrush currents like motors and transformers.

The Chint NXB-63 D10 3P is a miniature circuit breaker. Basic Product Information Breaking capacity 6kA per IEC 60898-1 DIN rail mounting, compact modular design Thermal-magnetic trip mechanism for overload and short-circuit protection High reliability and long electrical life Complies with international standards (IEC, GB) Rated current 10A, 3-pole design for three-phase applications Technical Specifications Version & Model Difference The NXB-63 series includes different trip curves (B, C, D) and breaking capacities (4.5kA, 6kA, 10kA). The D10 3P model features a D curve for high inrush loads, such as motors and transformers. Compared to the C curve (for general distribution), the D curve provides higher magnetic trip thresholds. This model is the 6kA version, suitable for industrial applications. Regional versions may have different certifications (e.g., CE, CCC). Application Scenarios Industrial control panels and motor control centers Commercial building electrical distribution boards HVAC equipment protection Machine tool electrical systems Replacement for existing MCBs in maintenance and retrofit projects What is the difference between D10 and C10 trip curves? The D curve has a higher magnetic trip threshold (10-20x In) compared to the C curve (5-10x In), making it suitable for loads with high inrush currents like motors and transformers. Is the Chint NXB-63 D10 3P a direct replacement for other brands? Yes, it is electrically and mechanically compatible with standard DIN rail mountings and can replace equivalent models from ABB, Schneider, Siemens, etc., in most applications. What is the warranty period for this product? We offer a 12-month warranty against manufacturing defects. Extended warranty is available upon request. What is the breaking capacity of the Chint NXB-63 D10 3P? The breaking capacity is 6kA, suitable for most industrial and commercial applications.
