R-Rated medium voltage fuses for motor
circuit protection
Features and benefits
•
Current-limiting R-Rated fuses will safely
interrupt all currents between their minimum
and maximum interrupting ratings and will melt
in a range of 15 to 35 seconds at a value of 100
times the “R” number per ANSI C37
.46.
R-Rated fuses are physically dimensioned for
easy installation in existing hardware.
Available in standard, AMPGARD Hookeye and
hermetically sealed, and bolt-on mounting styles
to meet application needs.
4.8 kV Limitamp
®
bolt-on constructions available
in ratings from 2R to 24R.
2.4 kV and 4.8 kV AMPGARD hermetically
sealed constructions are suitable for Class I,
Group D, Div. 2 hazardous locations.
Open fuse indicator on all mounting styles
speeds troubleshooting.
Classified as backup fuses for current-limiting
protection of medium voltage motor controllers
(short-circuit performance only).
These fuses are in a self-contained, non-venting
package for installation indoors or outdoors in
an enclosure.
