Mersen F301512 - Mersen 1250/1300V 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 four different body sizes, each size having seven worldwide acceptable mounting styles. The different mounting styles and body sizes long 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 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 interrupting rating. 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 onto the fuse even while in service. 1300 Volts 225 Amps size 71 TTI series.
