Fusetron® dual-element, time-delay fuses FRN-R (250V) Class RK5
Low Voltage, Branch Circuit Rated Fuses - Branch Circuit Rated Fuses
Fusetron® dual-element, time-delay fuses
FRN-R (250V) Class RK5
Specifications
Decription:
Dual-element, time-delay fuse - 10 seconds (minimum) at 500% rated amps (8 seconds for 0-30A sizes). Now available with optional permanent indication on select ratings (see Catalog Numbers table).
Construction:
Fiberglass tube.
Ratings:
Agency Information:
CE, Std. 248-12, Class RK5, UL Listed, Guide JDDZ, File E4273, CSA Certified, Class 1422-01, File 53787.
Features and Benefits:
@ Separate overload and short-circuit elements provide time delay for 125% of motor FLA sizing, linked with RK5 current
limitation.
@ 2:1 selective coordination amp ratio (within the Cooper Bussmann RK5 fuse family)
prevents overcurrent events from opening upstream Fusetron fuses.
@ Insulated end caps for 110A-600A fuses reduces exposure to live parts and extends air gap to distance between blades of adjacent mounted fuses or to housing.

Note::
@ For superior electrical protection, Cooper Bussmann recommends upgrading FRN-R fuse applications to Low-Peak LPN-RK fuses.
@ For fuse reducers, please reference data sheet 1118.
@ *Available with optional permanent indication. To order place "ID" at the end of the catalog number. Example: FRN-R-7ID.
@ RK5 Dimensions: basic dimensions are same as Class H (formerly NEC) One-Time (NON & NOS) and Superlag Renewable RES & REN fuses. NOTE: These fuses can be used to replace existing Class H, RK1 and RK5 fuses relating to dimensional compatibility.
