Are you looking for a simple but effective way to stop surges in their tracks? Add this cartridge fuse from Eaton to your setup. It's a sacrificial element that protects downstream devices from electrical damage by blowing and breaking the circuit if it receives a current over 7A. As the body is made out of transparent glass, it's a cinch to spot when the internal filament has melted. To restore your safety system, you just need to pop the burnt-out device out of its holder and slot in a fresh one.

• Nickel-plated endcaps resist rust for safe use in humid environments
• Brass endcap body is highly conductive to carry currents without a hitch
• Standard 5 (diameter) x 20mm (Length) dimensions to suit commonly used holders
• Low resistance of 12mΩ means the fuse causes minimal voltage drop so won't interfere with your circuitry

This is an F-type fuse, so it's fast-blowing. This makes it a reliable general-purpose option for protecting things like cabling or sensitive devices.
