Bolt fuse is a special overcurrent protection device for high current and high voltage circuits, adopting bolt wiring structure, with strong current carrying capacity, high breaking capacity and stable performance. It is mainly used in new energy vehicles, energy storage power stations, photovoltaic high voltage systems, industrial high-power equipment and other scenarios, solving the high current protection needs that ordinary fuses cannot meet.
The product’s rated current ranges from 30A to 600A, rated voltage covers 250V-1500V, divided into DC and AC types. Among them, DC bolt fuses are optimized for DC circuits of new energy and energy storage, with excellent arc extinguishing performance, avoiding arc hidden dangers caused by DC circuit short circuits. The material is made of high-quality copper alloy conductive parts, matched with flame-retardant insulating shell, high temperature resistant, corrosion resistant, and can adapt to harsh industrial and new energy working conditions.
Bolt fuses need to be used with bolt-on fuse holders, easy to install, and only need to replace the fuse body during maintenance without changing the line. Essfuse bolt fuses have passed professional power safety certifications, suitable for various high voltage and high current circuits, providing reliable protection for new energy and industrial equipment.
