Zhejiang Hongman Electric Technology Co., Ltd. is one of the most reliable manufacturers and suppliers of nt4 ceramic fuse link in China. We are committed to providing high quality customized products made in China with competitive price. Welcome to wholesale bulk cheap nt4 ceramic fuse link from our factory.
Product Introduction
Our 1250A Fuse Link, also known as HRC Fuse Link and Ceramic Fuse Link, adopts high-temperature resistant solid ceramic housing, filled with high-purity arc-quenching quartz sand . It is specially designed for low-voltage industrial power distribution, energy storage cabinets and large motor circuits. It can steadily carry rated current up to 1250A with excellent high rupturing capacity, cutting off overload and short-circuit faults instantly to protect busbars, transformers and high-power electrical equipment. Compliant with IEC60269 international standard, the ceramic shell features excellent insulation, pollution resistance and thermal shock resistance without cracking under long-term full-load operation. Thick Tin-plated pure copper terminals reduce power loss and ensure stable contact, matching 690V AC low-voltage systems. Our products are widely sold to Europe, America and Southeast Asia. We have over 10 years experience in electrical protection devices with full production lines, supporting bulk customization. We look forward to being your reliable long-term partner from China.
