                                                      Ferraz Shawmut 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 availa-
                                                      ble in three different body sizes, each size having four world-
                                                      wide 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 Ferraz Shawmut 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

                                                      I t 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.
