Overview
The Littelfuse FLS-R-2-ID is a Class RK5 dual-element time-delay indicator fuse rated for 2A at 600V AC. This fuse combines current-limiting protection with a patented visual indication system that clearly shows when the fuse has blown, eliminating guesswork during troubleshooting and maintenance. The dual-element design provides reliable short-circuit and overload protection, making it ideal for motor circuits and general industrial control applications where nuisance openings must be minimized.
Key Features
- Visual Indicator: Patented solid-state indicator clearly shows blown fuse status at a glance, reducing diagnostic time and equipment downtime
- Dual-Element Design: Provides advanced overload and short-circuit protection with minimal nuisance tripping
- Current Limiting: Class RK5 construction limits fault current, protecting downstream components
- Time-Delay Characteristic: Allows temporary inrush currents common in motor startup while protecting against sustained overloads
- Industry Standard: UL-listed and widely used in control panels, motor starters, and electrical distribution equipment
