MERSEN S300741 Square Body High-Speed Fuse Protistor® 2x73 aR 850VAC IEC 2800A With Striker Plates with Metric Threaded Holes

The 1250V Protistor® fuse-links provide maximum flexibility in equipment design and ultimate protection for today's power conversion equipment. These aR ultra-fast acting square body fuse-links are available in different body sizes, each size having multiple worldwide acceptable mounting styles.They have been engineered to provide state-of-the-art protection for semiconductors: diodes, thyristors and IGBT devices. They are assembled with die-cut elements embedded in solidified sand, which helps control arcing characteristics for a lower I²t and high interrupting rating level. All contact surfaces are silver plated and all hardware is non-magnetic.All fuse-links can be equipped with a low voltage trip-indicator which can operate a field mountable microswitch.
