High-quality 5 Amp 250V glass fuse in a standard 5x20mm size designed for electronic circuits, power adapters, home appliances, and protection boards. Fast-acting blow type fuse provides reliable overcurrent protection in compact electrical systems.
Ensure the vital protection of your sensitive electronic circuits and equipment with our high-quality 5A 250V Glass Fuse – 5x20mm Fast Blow Tube Fuse. This essential passive component is meticulously engineered to safeguard your devices from damaging overcurrents and short-circuit conditions, acting as a crucial first line of defense.
Designed as a fast-acting (or "fast blow") fuse, it features a filament that is specifically calibrated to melt and break the circuit almost instantaneously when the current exceeds its 5 Ampere rating. This rapid response is critical for protecting delicate and expensive components in modern electronics that can be severely damaged by even momentary current surges. With a 250 Volt rating, it is suitable for a wide array of low to medium-power AC and DC applications.
The compact 5x20mm physical size of this glass tube fuse makes it a universally compatible choice for various fuse holders and applications where space is at a premium. The transparent glass body allows for easy visual inspection, enabling you to quickly determine if the fuse has blown (indicated by a broken filament) without the need for additional testing equipment, simplifying troubleshooting and replacement
Common applications for our 5A 250V Fast Blow Glass Fuse include:
Consumer Electronics: Protecting power supplies in TVs, audio equipment, computer peripherals, and other household gadgets.
Small Appliances: Used in devices like blenders, coffee makers, and hair dryers (always verify the required fuse rating for your specific appliance).
Power Adapters & Strips: Safeguarding devices connected through adapters and surge protectors.
DIY Electronics Projects: Essential for prototyping and protecting circuits built with microcontrollers, sensors, and other components from unexpected current spikes.
Industrial & Commercial Equipment: Providing supplemental protection for internal circuits or components in a wide range of machinery.
By choosing our 5A 250V Glass Fuse, you are opting for reliable and proven overcurrent protection. Its quick-blow characteristic ensures that sensitive equipment is protected swiftly, minimizing potential damage and extending the lifespan of your valuable electronics.
