Time-delay – 10 seconds (minimum) at 500% of rated current. Features: • Provides motor overload, ground fault and shortcircuit protection • Helps protect motors against burnout from overloads and single-phasing when sized properly • Simplifies and improves blackout prevention (selective coordination) • Dual-element fuses can be applied in circuits subject to temporary motor overloads and surge currents to provide both high performance short-circuit and overload protection • The overload element provides protection against low level overcurrent of overloads and will hold on inrush current which is five times greater than the amp rating of the fuse for a minimum of ten seconds ® Specifications: Ratings • Volts • 250Vac • 125Vdc (110-200A) • 250Vdc (225-600A) • Amps 70-600A • Interrupting rating • 200kA Vac RMS Sym. • 20kA Vdc Agency information • • cULus Listed file No. JDDZ.E4273 • UL 248-12 – Class RK5 Fuses • CSA C22.2 No. 248.12 – Class RK5 Fuses CE Carton qty. 5 1 Technical Data 1020 FRN-R Class RK5 250Vac, 125/250Vdc 70-600A, dual element, time-delay fuses Effective July 2023 Dimensions - in: 5.88” 1.06” 70 to 100A 7.13” 1.56” 110 to 200A 8.63” ± 0.09 2.38” ± 0.02 225 to 400A 10.38” ± 0.09 2.88” ± 0.02 450 to 600A Recommended fuse blocks: Fuse amps 70-100 110-200 225-400 450-600 1-pole RM25100-1CR RM25200-1CR RM25400-1CR RM25600-1CR 2-pole RM25100-2CR RM25200-2CR RM25400-2CR RM25600-2CR 3-pole RM25100-3CR RM25200-3CR RM25400-3CR RM25600-3CR For additional information on the RM 250 volt fuse blocks, see product brochure no. 3192. use reducers for Class R fuses Fuse size 65 to 100A 110 to 200A 65 to 100A 110 to 200A Amp size of fuse block or disconnect switch 400A 600A 225 to 400A Catalog no.
