The Distribution Electrical Equipment Manufacturing Department I specializes in the production of low-voltage moulded case electrical equipment, covering an area of 29,000 square meters and divided into five operational areas. It annually produces over 25 million MCCB, RCCB, and other related products. Its core automated workshop focuses on the NXM-250 MCCB, a product that integrates five major systems: electromagnetic, operating, tripping, arc-extinguishing, and housing. Relying on DFM (Design for Manufacturability) optimization, the workshop achieves key component upgrades and automated assembly, leading the industry. The production line has an hourly output of 240 units, doubling the efficiency. The production line integrates 53 online detection technologies, including CCD and photoelectric sensors, for precise error prevention and quality assurance. Real-time detection and isolation of defective products ensure a 100% first-pass yield, with full traceability of the products throughout the process.
