R-RATED MEDIUM VOLTAGE FUSES

Description

Characteristics

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.

Voltage Ratings

Current Range

2,750 V – 8,250 V

2R – 36R

Options

• Hermetically sealed for use in hazardous locations

(add “S” sufﬁx to part number)

• Bolt-in mounting conﬁgurations

Hookeye Feature*

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.

For hookeye attachment; add “W” suffix

to part number
