E-Rated General Purpose Fuses
"E-rated" fuses are general purpose fuses that protect against
both low and high values of fault current. These fuses have timecurrent
characteristics designed to provide current limiting protection
for power transformers, power centers, feeder circuits and unit
substations.
E-Rated Potential Transformer Fuses
Potential Transformer (PT) fuses are current limiting fuses with
high interrupting ratings designed for the protection of potential
transformers.
R-Rated Back-Up Protection Fuses
"R-rated" fuses are designed to protect against only high values of
fault currents and should be applied only as back-up protection.
They provide required short-circuit protection for medium voltage
motors, motor controllers, and associated circuitry. However, they
must be used in series with other devices, such as motor overload
relays, to achieve both overload and short circuit protection.
