Ferraz Shawmut GSF2-1/2 is a high-speed semiconductor fuse designed for the protection of power diodes, thyristors, and other sensitive power electronic devices from overcurrents. This fuse is rated for 2.5 amperes at a maximum voltage of 250 volts AC/DC, providing reliable interruption of fault currents with a high AIC rating. The GSF2-1/2 features a compact, cylindrical body with blade-type terminals, constructed with a silver-plated copper element and a sand-filled ceramic body for superior arc quenching and thermal management. It complies with UL 248-13 and IEC 60269-4 standards for semiconductor fuse performance, ensuring consistent protection in demanding environments. Typical applications include variable frequency drives, uninterruptible power supplies, and DC power systems where precise overcurrent protection is critical.
