R-RATED MEDIUM VOLTAGE FUSES
Description
R-rated fuses provide required short-circuit protection for
medium voltage motors, motor controllers and associated
circuitry. These components have limited ability to absorb the
energy of large short-circuit currents. Medium voltage motor
controllers contain overload relays which provide both overload
protection and locked rotor protection to the motor. The
controllers are also intended to interrupt low value short-circuits
within the capability of the motor controller. This protects the
medium voltage fuse from sustained overcurrents which are
less than their minimum interrupting rating.
NEMA Standards for R-rated medium voltage power fuses
require they operate within 15-35 seconds when subjected
to an rms current 100 times the R rating. For example, a
fuse with a 2R rating will open within 15 to 35 seconds on
an applied current of 2 x 100 = 200 amperes.
