The JCK-A and JCL-A are standard JCK and JCL product
with an additional Westinghouse amp guard hookeye.
This single hookeye is on one end of the fuse and aids in the
insertion and removal of the fuse.
R-Rated medium voltage fuses are back-up current limiting
fuses used in conjunction with medium voltage motors and
motor controllers.
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 short-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.
