Description
High voltage fuse XRNM is current-limiting fuse for transformer protection
High-voltage fuses XRNT series manufactured by METTZ Group are intended for use in three-phase alternating current circuits with voltage from 7.2 to 40.5 kV, frequency 50/60 Hz; for protecting overhead and cable lines, power transformers, capacitors, electric motors from overcurrent during overloads and short circuits.
High-voltage current-limiting fuses of the High voltage fuse XRNM have a high breaking capacity. In electrical networks, XRNM fuses in combination with load switches can replace expensive power switches.
Overall, installation dimensions, appearance of fuses of the XRNM series meet the international standard IEC 60282-1.
Advantages:
— small dimensions save installation space
— response speed relative to other protective devices
— the ability to disconnect large short-circuit currents with a significant limitation of their maximum value
— overvoltage value is 1.5 times less than conventional PCT
— completely independent location in space
— the fuse holder body is made of high-quality heat-resistant porcelain, coated with a moisture-proof glaze
-fuse holder caps are made of electrotechnical copper with galvanic coating (tin plating), providing high current conductivity
-fuse holder filler, highly purified quartz sand, ensures effective extinguishing of the electric arc inside the fuse when it is triggered
