The NLW3-8000 delivers exceptional current-carrying capability, meeting the large-scale power distribution needs of heavy industries (e.g., steel mills and refineries). Its reinforced copper conductors minimize resistance and heat generation, supporting continuous high-load operation.
Equipped with an intelligent electronic trip unit, the breaker provides multi-layer protection against overload, short circuit, and grounding faults. It also records fault data (e.g., fault type and duration), simplifying post-fault analysis and maintenance.
The fixed long-bar structure enhances the breaker’s stability. It features a sturdy housing for anti-vibration performance, easy wiring to reduce installation time, and improved heat dissipation to prevent overheating during high-current operation.
Supporting communication protocols like Modbus, the NLW3-8000 enables real-time status tracking and remote diagnostics. This allows users to monitor power conditions remotely, reducing on-site maintenance costs and improving response efficiency.
Built with shock-resistant and wear-resistant materials, the breaker has an extended mechanical life. It maintains reliable performance after thousands of operations, reducing the frequency of replacements and lowering long-term operational costs.
In power plants and substations, the NLW3-8000 ACB acts as a core protection device. Manage high currents between generators, transformers, and distribution networks to prevent system failures.
Heavy industries (e.g., automotive manufacturing and mining) and rail transit systems require stable high-current distribution. The breaker’s high breaking capacity and heat dissipation ensure safe operation of large equipment and train power systems.
Data center server rooms and large commercial complexes (e.g., airports and malls) have high power demands. The breaker’s remote monitoring function helps manage power loads efficiently, ensuring uninterrupted service.
CHNAILE provides tailored solutions for the NLW3-8000 to meet project-specific needs:
Pole Customization: Options for different pole configurations to match various power distribution system requirements.
Communication Protocol Adaptation: Support for additional protocols (beyond Modbus) to integrate with customer’s intelligent management systems.
Branding & Packaging: Custom logo printing and packaging designs to align with customer brand standards.
It offers flexible pole options, which can be selected based on whether the system requires neutral line protection.
Yes. The breaker supports remote monitoring via communication protocols like Modbus, allowing users to check real-time status, fault records, and load data from a central control room.
The fixed structure enhances stability during high-current operation, while the long-bar terminal design simplifies wiring and improves heat dissipation—critical for preventing overheating in continuous high-load scenarios.
