Frn-r Series Bp/frn-r-15 Heavy-duty Fuse, 15 A, 250 Vac, 125 Vdc, 20, 200 Ka Interrupt, Fiberglass Body, Rk5

The Bussmann BP/FRN-R-15 is a heavy-duty, time-delay cartridge fuse designed to protect electrical circuits from overcurrent damage while allowing safe startup surges in motor-driven equipment. This Class RK5 fuse combines dual-element construction with Fusetron technology to deliver superior protection for motors, transformers, HVAC systems, refrigeration equipment, and industrial machinery. The time-delay characteristic prevents nuisance trips caused by brief inrush currents during motor startup, while still interrupting dangerous sustained overloads that could cause equipment burnout or fire.

By sizing cartridge fuses closer to actual load requirements, you reduce energy waste and improve circuit efficiency. The 2-pack format supports regular maintenance schedules and inventory management, keeping spare fuses on hand for quick replacement when needed. Bussmann's reputation for precision engineering and safety compliance makes this fuse a trusted choice for commercial and industrial applications that demand reliable performance and NEC standard adherence.
