• 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 are supplied with Westinghouse

Ampguard Hookeye.

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

inser tion 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 mini-

mum 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 shor t-circuit pro-

tection 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.
