The Bussmann Fusetron FRN-R-60 is a professional-grade, dual-element time-delay cartridge fuse engineered for high-performance circuit protection. Rated for 60 Amps and 250 Volts AC, this Class RK5 fuse features a current-limiting design that significantly reduces peak let-through current to protect sensitive downstream components. Its dual-element construction provides a minimum 10-second time delay at 500% of the rated current, effectively preventing nuisance openings caused by temporary motor start-up surges or harmless overloads. Built with a rugged fiberglass body and high-conductivity ferrule ends, it is specifically designed for use in motor control centers, machinery disconnects, and power panelboards. This fuse is an essential component for protecting motors against burnout from overloads and single-phasing in three-phase systems.
