"""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, GTOs 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."""
"""Mersen 1500 V PSC fuse-links provide maximum flexibility in equipment design and ultimate protection for today’s power conversion equipment. These square body fuse-links are available in three different body sizes, each size having four worldwide acceptable mounting styles. The different mounting styles and body sizes along with a broad range of ampere ratings allow greatest flexibility in equipment design. The Mersen PSC fuses have been engineered to provide state-of-the-art protection for SCR’s, diodes, thyristors, GTO’s and IGBT devices. They have pure silver die-cut elements embedded in solidified sand which helps control arcing characteristics for low I²t and high breaking capacity. All contact surfaces are silver plated and all hardware is non-magnetic. All fuse links are equipped with a low voltage trip-indicator. This trip-indicator can operate a field mountable microswitch which is easily mounted directly on to the fuse even while in service."""
