DC fuse is a protection device specially designed for DC circuits. Different from AC fuses, its core advantage is DC arc extinguishing performance. Because DC circuits have no zero crossing, short circuit arcs are difficult to extinguish. DC fuses adopt a special arc extinguishing structure, which can quickly cut off DC fault arcs, and are widely used in DC circuit scenarios such as new energy, energy storage, photovoltaics and automobiles.
The product’s rated voltage covers 12V-1500V, rated current covers 1A-2500A, covering all specifications of low voltage small current and high voltage high current, suitable for various circuits such as vehicle low voltage DC, energy storage/photovoltaic high voltage DC. It has the characteristics of flame retardancy, shock resistance and weather resistance, and can be used in industrial and outdoor scenarios. It has high protection accuracy and will not misoperate due to current fluctuation.
DC fuse is the core protection accessory of new energy DC circuits. High voltage DC specifications are selected for photovoltaic and energy storage systems, low voltage DC specifications are selected for automobiles and small electronic equipment, which must be perfectly matched with circuit voltage and current. Essfuse DC fuses are specially optimized for DC circuits, with reliable arc extinguishing, providing safety protection for various DC systems.
