Description
The Littelfuse FLSR025 is a 25 Amp Class RK5 dual-element time-delay fuse built for dependable overcurrent protection in demanding industrial and commercial power distribution applications. Rated at 600V AC, it is engineered to absorb short-duration inrush currents from motors and transformers without nuisance blowing, while maintaining robust protection against sustained overloads and short-circuit faults. The result is improved system uptime, reduced maintenance interruptions, and stronger protection for downstream equipment. Its current-limiting design and rugged cartridge construction make the FLSR025 a trusted choice for motor branch circuits, HVAC systems, and general industrial power distribution where consistent, long-term performance is non-negotiable.
