Zhejiang Yantai Electric Co., Ltd., a provincial-level high-tech enterprise rooted in Yueqing—the capital of China’s low-voltage electrical industry, has focused on the R&D, production and sales of high-quality low-voltage electrical appliances since 2002. Our core product includes RCCB (Residual Current Circuit Breaker), a critical protective device dedicated to personal electrical safety. This product specializes in earth leakage protection to effectively prevent electric shock hazards, acting as a vital safeguard for various electrical systems.

The core function of Yantai RCCB is to quickly and accurately detect leakage current in the circuit. Once abnormal leakage is identified, it immediately disconnects the circuit within milliseconds to protect personnel from electric shock, greatly reducing the risk of electrical accidents. It is important to note that this device focuses on leakage protection and does not provide overload or short circuit protection, making it a targeted safety component for specific application scenarios. All our RCCB products adopt strict design standards and undergo rigorous performance and aging tests, complying with CCC, CE, SEMKO certifications and ISO9001 quality management system, ensuring stable and reliable operation.
