Description
The Littelfuse FLM030 is a professional-grade 30-amp, 250-volt time-delay midget fuse built to safeguard industrial and commercial electrical systems against overloads and short circuits. Its dual-element, slow-blow construction intelligently distinguishes between harmless inrush currents and genuine fault conditions — eliminating nuisance interruptions while maintaining robust circuit protection where it matters most.
The compact 10×38 mm midget form factor allows straightforward installation into standard fuse holders, minimizing downtime during replacement or maintenance. With a high interrupting rating of 10kA at 250VAC, the FLM030 is engineered to handle demanding fault conditions safely and reliably — making it a trusted choice for protecting control transformers, solenoids, and small motor circuits.
