Fuse-links for the protection of semiconductors are conform to the international standard IEC 60269-4 respectively the german standard DIN EN 60269-4. They are available in utilization categories aR, gR and gS. Various contact types, diff erent rated voltages and rated currents adapted to the semiconductor devices allow for selection according to the specifi c application.
Semiconductor fuse-links with utilization categories aR, gR and gS for AC500V, AC690V and AC1000V are mainly applied for the protection of semiconductors as well as systems and devices.
• Utilization category aR serves as sole protection against short circuits. Overload protection has to be covered by separate measures. The series is optimized to especially low operating Joule integrals.
• Utilization category gR is suitable for overload as well as short circuit protection. Besides full-range semiconductor protection they can be applied as battery fuses in UPS circuits.
• gS fuse-links merge the characteristics of utilization categories aR and gG and therefore combine protection of semiconductors as well as cables and lines. Amongst other applications they protect variable speed drives and soft starters.
JEAN MÜLLER fuse-links for semiconductor protection off er an extensive limitation of short circuit current and low let-through energy values when interrupting currents. In addition they have a high breaking capacity and low switching voltages.
Performance data of installed fuses cannot be altered or adjusted, therefore mismatching and malfunctioning is prevented. Function and characteristics remain unchanged over decades.
Semiconductor fuse-links off er increased protection against corrosion through a special surface treatment, contact surfaces are silver plated. Power dissipation values of the melting elements have been optimised during long-time research and development. Rated current are adapted to those of semiconductor devices.
