Description
The Littelfuse FLSR008 delivers proven overcurrent protection for demanding industrial and commercial electrical applications. Its dual-element, time-delay design tolerates the temporary inrush currents common to motors and transformers, eliminating nuisance blowing during startup — while still responding decisively to sustained overloads and short-circuit conditions that can damage equipment and create safety hazards.
Built to Class RK5 standards, this cartridge-style fuse offers high interrupting capacity and robust fault protection, making it a trusted choice for motor control centers, power distribution panels, and transformer circuits where reliability is non-negotiable.
