Mersen 690/700V PSC square body fuses provide maximum flexibility in equipment design and ultimate protection for today's power conversion equipment. These square body fuses are available in four different body sizes, each size having more than 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. Mersen PSC fuses have been engineered to provide state-of-the-art protection for SCRs, diodes, thyristors, GTOs and IGBT devices. They have die-cut elements embedded in solidified sand which helps control arcing characteristics for low I2T and high interrupting rating. All contact surfaces are silver plated and all hardware is non-magnetic. All PSC square body fuses are equipped with a low voltage trip-indicator. This trip indicator can operate a field mountable micro switch which is easily mounted directly onto the fuse.
