の Schneider Compact NSX series molded case circuit breakers featurehighly reliable protection, 柔軟な構成, intelligent interconnection, and convenient operation and maintenanceas their core attributes. Covering a rated current range of 16A–630A, they are suitable for multiple scenarios such as low-voltage power distribution and industrial control, and boast both performance and digital advantages. A detailed analysis from core dimensions is provided below:
- 優れた保護性能
- Full Coverage of Breaking Capacity
It achieves a breaking capacity of 25kA–200kA (9 grades) 415Vで, and stably reaches 75kA–100kA at 690V. Adopting a dual rotary arc extinguishing structure, the short-circuit breaking time is ≤0.02s, delivering remarkable current limiting effect and effectively preventing fault escalation.
- Precise Tripping System
Thermomagnetic Trip (TM) : Suitable for conventional power distribution, it trips via bimetallic strip heating under overload conditions and triggers instantaneous electromagnetic action during short circuits, offering cost-effectiveness.
電子トリップ (マイクロロジック) : Supports three-stage protection including long-time delay, 短時間の遅延, and instantaneous tripping, with customizable curves. It is adapted to special loads such as motors and capacitors, avoiding false tripping.
- Comprehensive Selective Protection
Cascading technology enhances the breaking capacity of downstream devices, achieving full selectivity between upstream and downstream circuits, ensuring continuous power supply for non-faulty loops, and reducing the risk of system power outages.
- 残留電流保護
When paired with the Vigi module, it provides leakage protection to meet personal safety and fire prevention requirements, supporting action current selection ranging from 30mA to 500mA.
- Flexible Modular Design
- Multi-specification Adaptability
Available in frame sizes NSX100/160/250/400/630, with 3-pole or 4-pole options. It supports flexible switching between fixed, プラグイン, and draw-out mounting methods, adapting to different cabinet layouts.
- Plug-and-Play Accessories
Accessories such as undervoltage releases, シャントリリース, and auxiliary contacts are interchangeable on-site. Wireless auxiliary contacts (OFSD) and PowerTag energy modules require no wiring, enabling efficient installation and maintenance.
- Ease of Installation
The transparent cover allows visual inspection of module status. The ergonomic handle ensures effortless operation, and torque-limiting screws guarantee reliable wiring and assembly, reducing human error.
Ⅲ. Intelligent Digitalization and Energy Management
- Built-in Measurement Function
The Micrologic 5/6 series trip units can measure parameters such as current, 電圧, 力, and total harmonic distortion (THD). They support energy consumption statistics and fault diagnosis, with data uploadable to the FDM121 display unit via RJ45 interface.
- Wireless Interconnection Capability
The PowerTag module enables wireless energy monitoring, while OFSD contacts remotely feed back the switch status (オン/オフ). Integrated into the EcoStruxure architecture, it supports remote operation and maintenance as well as predictive maintenance.
- Full Lifecycle Digitalization
The laser-engraved nameplate features a QR code, which can be scanned to directly access electronic documents via Go2SE. It supports event logging and fault tracing, simplifying asset management.
- High Adaptability and Compliance
- Wide Voltage and Environmental Adaptability
With a maximum rated voltage of 690V, it is suitable for scenarios such as photovoltaic systems (800V) and wind power generation. It operates stably within a temperature range of -5℃~+40℃ and at an altitude ≤2000m (derating is required for higher altitudes). It also offers excellent resistance to vibration, 湿度, and heat.
- Compliance with International Standards
IECなどの規格に準拠 60947, UL 508, and NEMA AB1, and has obtained classification society certification, making it suitable for applications in industries, 商業, marine engineering, and other fields.
- Environmental Protection and Sustainability
Manufactured using recyclable materials with recycled cardboard packaging, it reduces the carbon footprint throughout its lifecycle and meets the requirements of green engineering.
