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.
