R-Rated Fuses

For Motor Circuit Protection

Medium Voltage

JCG, JCR-A, & JCR-B

• R-Rated medium voltage fuses are back-up current limiting

fuses used in conjunction with medium voltage motors and

motor controllers.

• The JCK-A, JCL-A, & JCR-A are supplied with Cutler-

Hammer Ampgard Hookeye.

• This single hookeye is on one end of the fuse and aids in the

insertion and removal of the fuse.

• Current limiting fuses may be designated as R-Rated if they

meet the following requirements:

1. The fuse will safely interrupt all currents between its

minimum and maximum interrupting ratings.

2. The fuse will melt in a range of 15 to 35 seconds at a

value of 100 times the “R’ number (ANSI C37.46).

• Bussmann R-Rated current limiting fuses are designed for

use with medium voltage starters to provide short-circuit

protection for the motor and motor controller.

• These fuses offer a high level of fault current interruption in a

self-contained, non-venting package which can be mounted

indoors or in an enclosure.

• Open fuse indication on all fuses.
