Description
The Littelfuse FLSR003 is a precision-engineered 3-amp, 600-volt time-delay Class RK5 fuse built to safeguard industrial and commercial electrical systems against overcurrent events. Its dual-element, current-limiting design intelligently distinguishes between harmless temporary inrush currents — common during motor startups and transformer energization — and genuine fault conditions, eliminating nuisance trips while ensuring fast, decisive protection when it matters most. The cartridge-style construction provides a secure, vibration-resistant fit in standard fuse holders and switchgear, making installation straightforward and reliable. With an interrupting capacity of up to 200kA AC, the FLSR003 is built to handle the most demanding electrical environments with confidence.
