Standard ceramic electrical fuses to BS1362 for UK 3 pin mains plugs.
Improve safety by matching the correct fuse value to your electrical equipment. Mains plugs tend to come supplied with a 5A or 13A fuse fitted but these values are often much higher than needed. The lower the value of fuse used the quicker it will blow in the event of a fault, resulting in improved safety. A 3A fuse is suitable for electrical equipment up-to 700W, this includes most electronic devices such as desktop computers and televisons.
