B300473 Mersen - Square Body High-Speed Fuse Protistor® Size 31 aR 690VAC IEC 700VAC UL 250A With Striker Flush ends UNC threads
Product type: Semiconductor Protection Fuses
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 I²t 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.
*Multiple body sizes and terminals or blades combination
*aR Class according to IEC 60269-4 and VDE 636-23
*Very low I²t for improved semiconductor protection
*Ultra fast acting
*Current limiting
*Superior cycling capability
