general information: provides motor overload, ground fault and short-circuit protection. helps protect motors against burnout from overloads. helps protect motors against burnout from single phasing on three phase systems. 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 an overload which is five times greater than the ampere rating of the fuse for a minimum of ten seconds. 1 / 10 a to 30a 0.56" ( 0.008) 2" ( 0.31) 35a to 60a 3" ( 0.31) 0.81" ( 0.008) catalog symbol: frn-r current-limiting dual-element, time-delay ?10 seconds (minimum) at 500% rated current (8 seconds for 0-30a sizes) ampere rating: 1 10 to 60 amperes voltage rating: 250vac (or less) interrupting rating: 200,000a rms sym. dc ratings: 20,000 aic @ 125vdc agency information: ul listed, std. 248-12, class rk-5, guide jddz, file e4273 csa certified, c22.2 no. 248.12, class 1422-01, file 53787 catalog numbers frn-r- 1 10 frn-r-1 8 10 frn-r-8 frn-r- 1 8 frn-r-2 frn-r-9 frn-r- 15 100 frn-r-2 1 4 frn-r-10 frn-r- 2 10 frn-r-2 1 2 frn-r-12 frn-r- 1 4 frn-r-2 8 10 frn-r-15 frn-r- 3 10 frn-r-3 frn-r-17 1 2 frn-r- 4 10 frn-r-3 2 10 frn-r-20 frn-r- 1 2 frn-r-3 1 2 frn-r-25 frn-r- 6 10 frn-r-4 FRN-R-30 frn-r- 8 10 frn-r-4 1 2 frn-r-35 frn-r-1 frn-r-5 frn-r-40 frn-r-1 1 8 frn-r-5 6 10 frn-r-45 frn-r-1 1 4 frn-r-6 frn-r-50 frn-r-1 4 10 frn-r-6 1 4 frn-r-60 frn-r-1 1 2 frn-r-7 frn-r-1 6 10 frn-r-7 1 2 fuseblocks for class r fuses (clip retaining spring standard, suffix ?? see data sheet 1110 terminal type (suffix no.) basic screw w/ box lug w/ 1 2 ? catalog pres. clip quick- amps poles number plate cu only connect 1 10 1 r25030-1 sr pr cr cor qr to 2 r25030-2 sr pr cr cor 30 3 r25030-3 sr pr cr cor 31 1 r25060-1 sr cr to 2 r25060-2 sr cr 60 3 r25060-3 sr cr fuse reducers for class r fuses equipment desired fuse catalog number fuse clips (case) size (pairs) 250v 60a 30a no. 263-r 100a 30a no. 213-r 60a no. 216-r 200a 60a no. 226-r carton quantity and weight ampere carton weight* ratings qty. lbs. kg. 0?5 10 0.40 0.181 17.5?0 10 0.50 0.227 35?0 10 1.00 0.453 *weight per carton. dimensional data fusetron dual-element, time-delay fuses class rk5 - 250 volt frn-r 1 10 -60a 10-08 bu-sb08353 page 1 of 2 data sheet 1019
