According to national electrical safety standards, accidents caused by leakage current account for 35% of all electrical disasters in my country each year. Properly installed residual current circuit breakers (RCDs) can reduce the risk of leakage current by more than 70%. In low-voltage terminal distribution systems, RCDs are crucial devices for preventing electric shock and electrical fires, bearing the important mission of protecting personal and equipment safety. Based in the low-voltage terminal distribution field, we focus on the core needs of leakage current protection and have developed and produced RCDs that, with their accurate leakage current detection, rapid response mechanism, and comprehensive protection performance, have become indispensable leakage current protection tools in various scenarios.
The core working principle of our RCDs is to detect the current imbalance in the circuit. When the leakage current exceeds a set value, it quickly cuts off the power supply, eliminating safety accidents caused by electric shock and line leakage at the source. Our products strictly adhere to national standards such as GB16916/GB16917. Optimized leakage current parameters are designed for different scenarios. For household use, they are compatible with a leakage current of ≤30mA, enabling rapid response to electric shock hazards. For industrial use, the leakage current can be set from 30-100mA, balancing protection performance with stable equipment operation, adapting to various leakage protection needs.
In terms of performance, our leakage circuit breakers integrate multiple protection functions. In addition to core leakage protection, they also integrate overload and short-circuit protection, providing a one-stop solution for various safety hazards in terminal power distribution. No additional protection devices are needed, simplifying power distribution layout and reducing installation costs. The products employ a patented anti-interference circuit design, effectively resisting surrounding electromagnetic interference and preventing accidental tripping, ensuring stable operation in complex electrical environments. The casing is made of highly flame-retardant and impact-resistant materials, possessing excellent insulation performance and meeting IP protection standards, making them suitable for humid environments such as bathrooms and kitchens, as well as complex scenarios such as outdoor work and industrial production.
Whether in residential bathrooms and kitchens, commercial building public areas, or outdoor gardens and industrial production lines, our residual current circuit breakers (RCCBs) offer precise compatibility. For humid environments, our products utilize a waterproof sealing process to enhance protection levels, making them suitable for concealed installations of devices such as smart toilets and electric water heaters. For industrial applications, we optimize anti-interference performance and load adaptability, enabling circuit protection for air conditioning, HVAC, and production line equipment. As a professional manufacturer of low-voltage terminal distribution products, we prioritize safety and rigorously control product quality. Every RCCB undergoes strict testing to ensure rapid leakage response and accurate protection, building a comprehensive leakage protection barrier for every user, making electricity use safer and more reliable.
