About 492121
gR high speed fuse links for semiconductors with striker gR cylindrical high speed fuse-links provide optimum protection of semiconductor devices (thyristors, triacs, diodes, rectifiers, static relays, ect.) provides protection of overloads and short circuits. Melting elements are specially designed to obtain low I2t values and reduce arc voltages to provide adequate selective coordination with upstream fuse links. Typical applications include protection of rectifiers, UPS, motor drives, soft starters and inverters. table.
