The automotive fuse and relay box is a critical automotive component designed to ensure the safety of circuits and electrical devices by preventing damage or fire caused by abnormal currents, which enhances the reliability and maintenance efficiency of circuits. It can accommodate multiple high-power relays to control high-power loads, and provides fast-melt and slow-melt fuses to accommodate different loads. The products utilize fully automated production processes, including advanced PCBA reflow soldering, automated pin insertion machines and fully automated assembly lines, along with optical inspection and functional testing to ensure efficient production, consistency and quality of the products.
