Fuse PKN 001-10 U3 version (GOST) Elektrofafor CB-00001842

High-voltage fuses PKN 001-10 U3 are designed to protect voltage transformers at rated voltages of 3, 6, 10 kV. PKN 001-10 U3 fuses with quartz filler are current-limiting. The interruption of short-circuit current in fuses with quartz sand is ensured by the intensive deionization of the arc arising at the location of the fuse link in the narrow gaps between the sand grains of the filler. The operation of the holder in PKN 001-10 U3 fuses is determined by the absence of readings from instruments connected to the voltage transformer circuit. High-voltage fuse PKN 001-10 U3 is a kit consisting of the following elements and is supplied disassembled: - Holder (replaceable element) PN 0.1-10 U3 – 1 pc. - Contact K01-10 U3 – 2 pcs. - Support insulator IO-10-3.75 U3 (M8 bolt/M12 bolt) – 2 pcs. The use of high-voltage fuses PKN 001-10 U3 in networks with voltages of 3 and 6 kV is permitted. Voltage class: 10 kV Holder diameter: 55 mm Holder length: 212 mm Climatic version: U3 Weight, kg: 4.20
