Power semiconductors as diodes and thyristors may be particularly damaged by short-circuit stress and long-time overcurrents.
JEAN MÜLLER HRC-fast fuse-links are extremely fast acting and therefore provide reliable over-current protection of sensitive semiconductor devices and effectively avoid substantial damage.
JEAN MÜLLER HRC-fast fuse-links are characterized by a distinct current limitation and a high breaking capacity. The use of high-grade materials, especially silver melting elements, guarantees a maximum ageing resistance.
The product range comprises fuse-links according IEC 60269-4 for reliable partial and full-range protection of semiconductor devices in all established NH types with blade, screw and thread contacts and rated voltages up to 1000V.
The offered different fast characteristics of the IEC utilization categories gS, gR and aR offer the possibility to adapt to the specific application.
