This kenable 1A 20mm glass fuse is for anyone needing to protect electronic circuits and devices from overcurrent and short circuits. Its key benefit is providing reliable circuit protection by sacrificing itself to prevent damage. A potential caveat is its specific 1A rating, meaning it's unsuitable for circuits requiring higher current. This fuse acts as a deliberately weaker component designed to fail safely, safeguarding more expensive equipment.

'Quick Blow (F)' signifies that the fuse is designed to react very rapidly to overcurrent situations, interrupting the circuit much faster than a 'Slow Blow' or 'Time Delay' fuse.
No, you should not use a higher amperage fuse. If the 1A fuse is repeatedly blowing, it indicates an underlying problem in the circuit that requires investigation and repair. Using a higher-rated fuse can lead to equipment damage or fire hazards.
The break capacity is 35A or 10 times the rated current (10In) at 250VAC, whichever is greater. This means the fuse can safely interrupt fault currents up to this level without exploding or causing further damage.
This fuse is rated for a maximum of 250V AC or DC. It should not be used in circuits operating at voltages higher than 250V.
Visually, the filament inside the glass tube may appear broken or blackened. For certainty, you can test the fuse for continuity using a multimeter.
DC cold resistance refers to the electrical resistance of the fuse element when it is at room temperature and before any current has passed through it. The value of 64-96mΩ is very low, indicating minimal resistance during normal operation.
This indicates a short circuit in the device or wiring. Disconnect power and inspect the circuit for damaged wires, faulty components, or incorrect wiring.
Ensure the fuse is the correct rating (1A) and is properly seated in the holder. Check that the fuse itself is not faulty (use a multimeter if possible). If the fuse blows again, refer to the 'Fuse blows immediately' issue.
The fuse may have a poor connection in the holder or the circuit issue lies elsewhere. Check the fuse holder contacts for corrosion or damage. Test the fuse with a multimeter for continuity.
