Description
The Littelfuse FLSR006 delivers proven overcurrent protection where reliability is non-negotiable. Engineered for demanding industrial and commercial applications, this 6A, 600V time-delay fuse features a dual-element, current-limiting Class RK5 design that intelligently distinguishes between harmless temporary inrush currents and genuine fault conditions — eliminating costly nuisance openings while ensuring fast, decisive response when it matters most. Its rugged cartridge-style construction provides secure, vibration-resistant installation in standard fuse blocks, panelboards, and switchgear. Whether protecting motor control centers, transformers, service entrance equipment, or general power distribution circuits, the FLSR006 offers the high interrupting capacity and time-delay performance that industrial environments demand.
