500mA 250V 3.9x11mm Miniature Glass Fuse Standard Recovery Rectifiers Brand Hi Link Model numberMiniature Glass fuses are ideal for providing protection to devices or internal circuits from short circuits and overcurrent. They are deliberately weaker components that, 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.
