gR High speed fuses for semiconductors
Cylindrical high speed fuse-links intended for the optimum protection of semiconductor devices (Thyristors, triacs, diodes, rectiÍ ers, static relays, etc). gR class allows protection in whole range of over-currents, overloads as well as short-circuits, protecting semiconductor devices and conductors and other switchgear installations. Typical applications comprise protection in rectiÍ ers, UPS, converters, motor drives, soft starters and inverters.
Melting elements are specially designed to obtain low I2t values, reduced arc voltages and an adequate selective coordination with upstream fuse-links. Wide range of rated currents and striker versions for use in fuse bases with micro-switch. Made of ceramic tube with high withstand to internal pressure and thermal shock, that allow a high breaking capacity in a reduced physical space. Contacts caps are made of silver plated copper.
