Fuse, Fast Blow, 5mm x 20mm – 250V AC, Range
The fuse is rated for 250VAC, and depending on which version you select, from 0.5A right up to 20A.
Fuses are pretty simple devices. If more than the rated current passes through the fuse, the small filament inside the fuse heats up and breaks (like a light bulb burning out). The circuit is then broken and hopefully, your circuit is saved from molten destruction.
- Glass Cartridge
- Low breaking capacity
- Nickel-plated brass endcap construction
- Designed to UL/CSA 248-14
- Diameter: 5mm
- Length: 20mm
- For smaller loads, you may want to check out a PTC (aka resettable fuse). These handle less current (500mA) but can be set and reset many times without doing harm to your system.
