Square Body High-Speed Fuse Protistor® Size 31 aR 690VAC IEC 700VAC UL 630A With Striker Flush ends UNC threads

The 690/700V 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 I..t and high interrupting rating level. All contact surfaces are silver plated and all hardware is non-magnetic.Each fuse-link can be equipped with a low voltage trip-indicator which can operate a field mountable microswitch.
