Medium Voltage Fuses

Medium Voltage, Fuse,: Medium Voltage Fuses are current limiting, power fuses having voltage ratings from 0.6kV to 34.38kV. Continuous current ratings range from 0.5 to 1,200 amps. E-rated medium voltage fuses are general purpose fuses that are primarily used to protect transformers and provide both current overload, and short circuit, protection. R-Rated fuses are back-up fuses primarily used to protect motors and motor controllers. R-Rated fuses only provide short circuit protection. Other medium voltage fuses are designed to protect potential transformers, capacitors and distribution transformers. Medium Voltage fuses are designed in accordance with the American National Standards Institute (ANSI). Back-up fuses designed in accordance with IEC Standards are also available.
