ABB OF series fuse links are specifically designed to react to temperature rise and as such limit current very reliably. The OF series of fuse links contain granulated quartz which binds the temperature generated by the arc in the short circuit. At the same moment the pressure within the OF series fuse link rises and the fusing element ruptures.
The ABB gG HRC fuse link is suitable for a number of applications, from over-current and short-circuit protection of lines to short-circuit protection of semiconductor and other equipment's. This fuse link guarantee maximum protection against all faults. It is rated for 20A current and has 2.3 W power loss.
