The FRN-R-2-1/2 Fuse is a dual-element time-delay Class RK5 fuse designed for reliable overcurrent and short-circuit protection in industrial and commercial electrical systems. Engineered with current-limiting performance, it protects motors, transformers, control panels, and branch circuits from overload conditions while allowing temporary inrush currents without nuisance tripping. Its durable cylindrical construction and high interrupting capacity make it ideal for demanding industrial applications.
