Description
Dependable Overcurrent Protection for Industrial and Commercial Applications
The Littelfuse FLSR020ID is a 20 Amp Class RK5 dual-element time delay indicating fuse engineered for reliable overcurrent protection in demanding industrial and commercial electrical systems. Rated for 600V AC, it safely absorbs temporary motor inrush currents without nuisance blowing, while delivering robust defense against sustained overloads and short-circuit faults. The integrated blown-fuse indicator enables instant visual fault identification, dramatically reducing diagnostic time and getting operations back online faster. With its current-limiting design and high interrupting capacity, the FLSR020ID is the dependable choice for motors, transformers, and power distribution circuits where uptime and safety are non-negotiable.
