Effective October 2018 Technical Data 6001 Supersedes August 2018 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). Description: These fuses are in a self-contained, non-venting Indoor/enclosure, R-Rated medium voltage, package for installation indoors or outdoors in current-limiting fuses for motor circuit an enclosure. protection.
