Description
The Littelfuse FLSR.600 delivers robust, high-capacity overcurrent protection for industrial and commercial electrical systems where reliability and safety are non-negotiable. Its dual-element, current-limiting design intelligently tolerates harmless temporary inrush currents — eliminating nuisance trips — while responding rapidly to dangerous overloads and short-circuit faults. Rated at 600 amps and 600 volts with an interrupting capacity of up to 200kA AC, this fuse is purpose-built for high fault-current environments. The heavy-duty cartridge-style construction ensures a secure, vibration-resistant fit in standard fuse holders and switchgear. Whether protecting service entrance equipment, transformers, motor control centers, or large-scale power distribution systems, the FLSR.600 provides the dependable fault protection your system demands.
