As a leading industry in China, our 800A 500V Square Type Fuse is a square tube bolt fast fuse product that is already very sophisticated and can meet the needs of domestic and foreign customers. The rated voltage of the 800A 500V square fuse core is 500V, with a breaking capacity of 50Ka, providing good safety protection and better equipment protection.

After hearing many customer demands, we have launched the 500V 63A NT00C fuse series square ceramic fuse, which is a high-performance electrical protection device that solves customer problems. Widely used in industrial and commercial applications. The 500V 63A NT00C fuse has a rated current of 63A and a rated voltage of 500V, which can effectively protect electrical equipment and wiring from overload and short circuit damage.

415V 355A JPU Bolt Fuse If the system fails, the fault current causes the fuse to melt immediately and an arc occurs, causing the arc extinguisher to be heated and explode a large amount of gas. This will create high pressure and blow off the arc with a tube. The 415V 355A JPU Bolt Fuse has passed the test of safety, precision and accuracy, with strong quality assurance, and the fuse tube is fixed to form a tight position when it is tightened by the fuse to work normally.

We use standard thickness copper silver plated RGS4 fast fuse, which has good conductivity. We use high-quality ceramic body and filled quartz sand that has been chemically treated to ensure excellent heat dissipation and arc extinguishing. 660-1000V Bolt Fuse can also be used for semiconductor components and short-circuit protection (aR) and motor protection (aM), with a rated voltage of up to 1000V, a rated current of 160A, and a working frequency of 50Hz. The rated breaking capacity of 660-1000V Bolt Fuse is up to 80KA, which complies with GB13539 and IEC269 standards.

Zhenghao has advanced technology, and our 500V 250A Fuse Base can provide excellent performance in use, making it very suitable for industrial and general applications such as cables, flexible strings, and other equipment to provide absolute protection for medium voltage circuits. The 500V 250A Fuse Base has been praised both domestically and internationally for its long service life, and Zhenghao has a strong competitive market price to offer to our customers. 500V 250A Fuse Base complies with IEC and CCC standards, solving customers' worries and ensuring reliable procurement and use.

400A 500V Fuse Base series fuse BASE is suitable for AC 50Hz, rated voltage to 500V, rated current to 400A. It is mainly used for protecting the electrical circuit against overload and short-circuits(gG/gL). Because of different melting tablets, it also may derive for protecting the semiconductor device and others complete set installment from short-circuit (aR/gR/gs) as well as the electric motor from short circuit (aM). The 400A 500V Fuse Base rated breaking capacity is to 120KA. They conform to national standard GB13539 and international electrical committee standard IEC60269.
