FAQs
BP/FRN-R-45 uses ferrule-end connections and a 3 in body which fits standard control-panel bussing and duct layouts. Ensure space for the dual-element construction and align the fuse holder to prevent bending or misalignment. Timer-rated operation supports normal motor startup surges, reducing nuisance trips while preserving protection.
The device is rated at 45 A with a 12-second response at 500% of rated current. It provides an interrupt rating of 200 kAIC on AC and 20 kAIC on DC circuits, supporting robust protection for short-circuit events without excessive clearing time that would disrupt operation.
Yes. The 45 A, RK5-class, time-delay, current-limiting design suits motor control and drives in conveyors and machine tools. It balances surge tolerance during startup with fast fault clearing, helping to minimize downtime and protect wiring insulation and control electronics from high fault currents.
The BP/FRN-R-45 is CE marked and falls under the RK5 protection class, which aligns with common European standards for fuses used in industrial control. While UL listings are not specified here, CE and RK5 compliance provide a solid regulatory basis for many European installations and OEM panel builds.
Maintenance is typically limited to periodic inspection and field replacement after a fault condition. The time-delay design helps avoid nuisance trips, reducing unplanned downtime. With reliable interruption performance and standardized Bussmann series sourcing, you can minimize spare-part variety and shorten repair cycles, delivering a favorable total cost of ownership.
