| I. Product Overview and Positioning | ||||||||
| 1. Compact NSX Series (100A-630A): As Schneider Electric's new generation flagship molded case circuit breaker, the NSX series emphasizes high performance and digitalization. It integrates precise measurement, power management, and communication functions, making it suitable for commercial buildings, data centers, and industrial facilities with extremely high requirements for intelligence and power supply continuity. | ||||||||
| 2. NS High Current Series (630b-1600A): As an extension of the NS series, the NS630b-1600A is mainly designed for high current power distribution scenarios. It fills the gap between molded case circuit breakers and frame circuit breakers (ACBs), providing an extremely compact high current solution, especially suitable for transformer secondary side incoming lines and large-capacity switchgear. | ||||||||
| II. Key Highlights of the Compact NSX Series (100A-630A) | ||||||||
| 1. Dual rotating contact technology:Inheriting Schneider Electric's proprietary dual-rotating contact structure and combined with the "Reflex" energy trip system, it uses gas pressure to accelerate tripping during short-circuit faults, greatly limiting the impact of fault current on downstream equipment and ensuring that Ics = 100% Icu (operating breaking capacity equals ultimate breaking capacity), fundamentally guaranteeing power supply continuity. | ||||||||
| 2. Precise Measurement and Communication:Equipped with a built-in dual-core current transformer, it can accurately measure electrical parameters such as voltage, current, power, and energy. It supports "plug-and-play" communication network architectures (Modbus, CANopen, Profibus, etc.), allowing it to be connected to the EcoStruxure smart power distribution system without additional wiring, enabling energy efficiency management and predictive maintenance. | ||||||||
| 3. Zone Selective Interlocking (ZSI):In complex power distribution networks, the ZSI function ensures that when a fault occurs, the fault is cleared only by the circuit breaker closest to the fault point, while the upstream circuit breaker remains closed, maximizing the power supply continuity of non-faulty circuits. | ||||||||
| 4. Modular attachment system:Employing Vigi integrated or modular leakage protection, it supports multiple auxiliary contacts such as OF/SD/SDE, and can be flexibly configured according to site requirements. | ||||||||

| Tripping Unit Selection Guide | ||||||||
| I. TM-D Thermomagnetic Type:It is suitable for conventional power distribution protection. Overload protection uses thermal bimetallic protection, and short circuit protection uses electromagnetic tripping. It has a high cost performance and a narrow adjustable range of setting current. | ||||||||
| II. Micrologic Electronic Type:Suitable for scenarios requiring precise protection, measurement, or communication: | ||||||||
| 1. Micrologic 2.2 / Micrologic 2.3:Basic electronic protection provides overload long-delay, short-circuit short-delay, and short-circuit instantaneous protection (three-stage protection). | ||||||||
| 2. Micrologic 5.2A/5.2E /5.3A/5.3E:Based on version 2.2/2.3, an electrical energy measurement function has been added, which can measure parameters such as power and electrical energy. | ||||||||
| 3. Micrologic 6.2A/6.2E /6.3A/6.3E:Based on version 5.2/5.3, a harmonic measurement function has been added, making it suitable for scenarios sensitive to power quality. | ||||||||

| 1. High current filling capability:The NS630b-1600A series is specifically designed for high-current applications, with rated currents ranging from 630A to 1600A, meeting the main protection requirements of large building incoming line cabinets and industrial distribution cabinets. | ||||||
| 2. High current limiting capability:It has extremely strong current limiting characteristics, which can quickly cut off the fault current when a short circuit occurs, significantly reducing the stress and thermal damage of short circuit current to lines and equipment, and extending the service life of equipment. | ||||||
| 3. Compact structural design:Compared to frame circuit breakers of the same specifications, the NS high-current series is more compact in depth and height, which helps to reduce the size of the distribution cabinet and save floor space and cabinet costs. | ||||||

| IV. Environmental Adaptability and Certification | ||||||
| Schneider's molded case circuit breakers undergo rigorous testing to adapt to various complex environments: | ||||||
| Operating ambient temperature:-25°C to +70°C (above +40°C, derating is required; refer to the technical manual for specific derating factors). Storage temperature: -50°C to +85°C. | ||||||
| Storage temperature:Storage temperature: -50°C to +85°C. | ||||||
| Resistance to damp heat:It complies with IEC 60068-2-30 standards and can withstand harsh environments of 55°C and 95% relative humidity. | ||||||
| International Certification:CCC (China Compulsory Certification), CE, IEC 60947-2 standard, classification society certifications (BV, LR, DNV), etc., meet global market access requirements. | ||||||
| V. Selection Recommendations | ||||||
| Your needs | Recommended choice | Core reason | ||||
| Requires power measurement and communication functions, current ≤630A | Compact NSX + Micrologic 5.x/6.x | Built-in current transformer, supports EcoStruxure, highly intelligent, and provides strong power supply continuity assurance. | ||||
| Motor protection is required, current ≤250A | Compact NSX + MA Electromagnetic Trip Unit | Specifically designed for motor circuits, it works in conjunction with contactors to provide comprehensive protection. | ||||
| For current between 630A and 1600A, I don't want to use a frame circuit breaker. | NS High Current Series (NS630b-1600A) | Filling the gap between the plastic shell and the frame, with a compact structure and high cost performance. | ||||
| Only basic overload and short-circuit protection is required; budget sensitive. | Compact NSX + TM-D Thermomagnetic | Reliable performance, high breaking capacity, meeting conventional power distribution needs | ||||
| The main incoming line on the secondary side of the transformer needs to achieve full selectivity protection with the downstream side. | NS High Current Series + Electronic Trip Unit (with Short Delay) | It has short-term withstand capability, enables fault isolation, and ensures the continuity of main power supply. | ||||
| Scene 1:Smart Buildings and Data Centers | ||||||
| Recommended products:Compact NSX (100A-630A) + Micrologic 5.x / 6.x + Modbus communication | ||||||
| Advantages of the solution:The NSX features built-in precision measurement capabilities, using Micrologic electronic trip units to monitor circuit energy consumption, load rate, and harmonics in real time. It connects to the EcoStruxure Power platform for remote operation and maintenance, improving the accuracy of energy efficiency management and ensuring power continuity for data centers. | ||||||
| Scene 2:Industrial control cabinets and motor protection | ||||||
| Recommended products:Compact NSX (100A-250A) with MA electromagnetic trip unit | ||||||
| Advantages of the solution:The NSX series offers electromagnetic trip units (MA) specifically designed for motor protection. It provides short-circuit protection only, while overload protection is handled by thermal relays. It works perfectly with contactors to achieve efficient protection of motor circuits and prevent false tripping. | ||||||
| Scene 3:Large capacity power distribution main incoming line | ||||||
| Recommended products:NS High Current Series (NS1000/NS1250/NS1600) + Electronic Trip Unit | ||||||
| Advantages of the solution:As the main incoming line switch on the secondary side of the transformer, the NS high-current series has short-time withstand capability. Combined with the short-delay function of the electronic trip unit, it can achieve full selective protection with the downstream NSX molded case circuit breaker, ensuring that only the faulty branch is disconnected when a fault occurs, without affecting the main power supply. | ||||||
| Scene 4:Industrial plants and commercial complexes | ||||||
| Recommended products:NS High Current Series (Main Incoming Line) + Compact NSX (Distribution Circuit) | ||||||
| Advantages of the solution:The combination of the two forms a complete molded case circuit breaker power distribution solution, from 630A-1600A incoming lines to 16A-630A branch circuits, achieving full-series protection matching and simplifying selection, spare parts and operation and maintenance management. |
