Audited Supplier It can be used in indoor system of 50HZ and rated voltage of 3.6KV, 7.2KV, 12KV, 24KV, 40.5KV used together with other switch facilities such as loading switches, vacuum contractors, it can protect electric transformers and other electric facilities against overloading or circuit break. it is also a necessary accessory for high-voltage switch.
High breaking capacity: The rated breaking current of the product is 40KA~50KA. Low power loss: ensures a low temperature rise of the product, which is more advantageous when fuses are used in fully enclosed insulation devices. Low arc voltage: During the breaking process, the arc voltage is low, and when used in systems below the rated voltage, the arc voltage will further decrease, which can be used for 12KV or 7 There is no danger of damaging the insulation of the 2KV system. Small characteristic curve error: The error of the time current characteristic curve is less than ± 10%, ensuring the reliability of the product. Standardization of specifications: The rated parameters of the product comply with the International Electrotechnical Commission (IEC) standards R10 and R20 series. There are two types of wiring:
(1) Busbar type, with overall dimensions in accordance with British (BS) standards;
(2) , plug-in, with external dimensions in accordance with German (DIN) standards;
Moreover, they all comply with the International Electrotechnical Commission (IEC) standards. The busbar type can be directly fastened to the busbar with screws, which has the advantages of small installation volume and reliable contact; The plug-in type is easy to replace and can be operated with power.
Can be equipped with an impactor: Tungsten wires in parallel with the melt can melt within a few thousandths of a second at the beginning of the arc, igniting the powder device. The firing pin operated by a small amount of gunpowder immediately acts and provides a signal with sufficient energy, or causes other electrical appliances to act, or provides interlocking. The output energy of the fuse impactor that meets the British (BS) standard is (1-3) joules, while the output energy of the fuse impactor that meets the German (DIN) standard is (2-5) joules.
