Application Summary AI generated
This standard specifies the performance requirements, test methods, and selection rules for high-voltage fuses used in railway rolling stock electrical systems. It applies to fuses designed for circuits with voltages above 1,000V AC or 1,500V DC, ensuring safe overcurrent protection in locomotives, electric multiple units, and other rail vehicles. The standard is used by manufacturers and railway operators to verify fuse reliability under operational conditions like vibration, temperature extremes, and short-circuit faults.
