Semiconductor Protection Fuses

British Standard High-Speed Fuse-Links AC Protection

Protistor® BS88-4 17x49 aR URZ/URY 690VAC (IEC)

The 690V Protistor® BS88-4 fuse-links provide maximum flexibility in equipment design and ultimate protection for protection of power semiconductors.These fuse-links are defined as per IEC 60269-1 and -4 , VDE 636-23 and BS88-4 for a worldwide acceptance.The Protistor® have been engineered to provide state-of-the-art protection for semiconductors: diodes, thyristors, GTO's and IGBT devices. Fuses are assembled with pure silver, die-cut elements embedded in solidified sand, which helps control arcing characteristics for a lower I²t and high interrupting rating level. Each fuse-link can be equipped with a low voltage trip-indicator which can operate a field mountable microswitch.
