From the shop's description

Glass Fuse T5 (800mA-250V) Glass cartridge fuses are ideal for protecting devices or internal circuits from short circuits and overcurrent. They are deliberately weaker components which, when too much current is drawn, will blow. Once the fuse has blown it will need replacing in order to make the circuit complete and allow the flow of current.
