Description
The Littelfuse FLSR.500 is a precision-engineered 0.5-amp, 600-volt time-delay Class RK5 fuse built to deliver dependable overcurrent protection across a wide range of industrial and commercial electrical applications. Its dual-element, current-limiting construction is designed to ride through harmless temporary inrush currents — eliminating nuisance blowing — while responding rapidly and decisively to true overloads and short-circuit faults. The compact cylindrical cartridge form factor ensures secure, reliable seating in standard fuse holders and switchgear, making the FLSR.500 an ideal solution for safeguarding control circuits, transformers, and sensitive low-current equipment. With a high interrupting capacity and a proven track record of long-term reliability, this fuse performs consistently even in the most demanding service conditions.
