QS High-Speed Round Body Fuses

Littelfuse QS Series High-Speed Round Body Fuses provide circuit protection at the fast speeds required by modern semiconductor devices. These fuses offer extreme current limiting protection against power surges and balanced performance for longevity. L50QS and L70QS series high-speed fuses use arc-quenching stone sand to provide lower arc voltages while offering reduced l2t let-through energy and peak currents. This improved performance differentiates the QS series from other power fuses, including previous S series fuses. Universal mount bolted-end terminals give these RoHS and REACH-compliant fuses the ability to replace existing fuses in the field easily. Littelfuse QS series fuses are ideal for drive panel builders, the oil and gas industry, pulp and paper industries, motor controls, wastewater treatment plants, and other large factory settings.
