Description
Product Positioning
This residual current circuit breaker is specifically designed for high-power electrical applications and serves as a core protection device for commercial complexes, large factories, outdoor power distribution projects, and new energy power plants. It addresses safety issues such as leakage, overload, and short circuits in high-power circuits, providing comprehensive and highly reliable protection for large power distribution systems. Capable of handling high currents while providing precise protection, it is the preferred choice for large-scale electrical applications.
Materials and Craftsmanship
The casing is made of high-strength, flame-retardant engineering plastic, treated with special impact-resistant and anti-aging agents to withstand harsh outdoor environments and complex industrial workshop conditions, effectively preventing safety issues caused by casing damage.
The core conductive components are made of high-purity, premium copper, precision-forged and surface-treated for corrosion resistance, reducing conductive losses, improving load-bearing capacity, and extending service life, enabling long-term high-power operation.
The production process strictly follows the ISO9001 quality management system and IEC 61008 international standards. Each unit undergoes multiple withstand-voltage and leakage-current tests to ensure stable operation under heavy load conditions.
Core Advantages
Fully compliant with international and national electrical standards.
High-precision leakage current detection with rapid response, immediately disconnecting circuits in case of leakage to prevent electric shock and fire hazards.
Integrates multiple protection functions including overload, short-circuit, and overvoltage protection, accurately adapting to high-power load fluctuations to prevent equipment damage and ensure continuous system operation.
Designed for high-current applications, with easy installation, flexible incoming line methods, simple maintenance, and a self-test function for real-time monitoring of operating status.
Stable, durable, and capable of reliable performance under long-term heavy load conditions.
Application Value
Suitable for main power distribution in commercial complexes, protection for large industrial equipment, and supporting protection for large outdoor power distribution projects and new energy power plants. Its high current-carrying capacity eliminates the need for additional protection devices, simplifies power distribution system construction, and reduces overall costs. Compared with similar products, it offers superior stability, load-bearing capacity, and durability, ensuring reliable operation even under sustained heavy-load conditions.
