Description
The Littelfuse FLSR005 delivers proven overcurrent protection where reliability matters most. Rated at 5 amps and 600 volts, this time-delay Class RK5 fuse is purpose-built for the demanding conditions of industrial and commercial electrical systems. Its dual-element, current-limiting construction intelligently tolerates the temporary inrush currents common in motor and transformer startup — eliminating nuisance openings — while responding rapidly to genuine overload and short-circuit events to safeguard equipment and personnel. The cartridge-style form factor ensures a secure, vibration-resistant fit in standard fuse blocks, panelboards, and switchgear, making installation straightforward and maintenance hassle-free.
