Semiconductor Protection Fuses

High performance square body fuse-links AC protection

Protistor® size 93 aR 1500VAC

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.
