These square body fuse-links are available in various body sizes with a broad range of ampere ratings allowing the greatest flexibility in equipment design. The Mersen PSC-LR fuse range has been engineered to provide state of the art protection for high power semiconductors such as diodes, thyristors, GTO’s, IGCT’s and IGBT’s. They have pure silver fuse elements embedded in solidified sand which provides optimized I²t and high interrupting rating. All contact surfaces are plated and all hardware non-magnetic. All fuses are standard with a low voltage blown fuse indicator. This indicator can operate a microswitch which is easily mounted directly on to the fuse in service.
