Square Body High-Speed Fuse Protistor NH Size 1 aR 690VAC IEC 700VAC UL 250A With Double indicator Plain Blades

The 690/700V Protistor fuse-links provide maximum flexibility in equipment design and ulitmate protection for today’s power conversion equipment. These NH style fuse-links are defined as per DIN 43620/00 for a worldwide acceptance into NH modular system fuse-holders, fuse switch disconnectors for direct installation. The Protistor have been engineered to provide state-of-the-art protection for semiconductors: diodes, thyristors, GTO’s and IGBT devices. Fuses are assembled with pure silver, die-cut elements embedded in solidified sand, which helps control arcing characteristics for lower and high interrupting rating level. All contact surfaces are silver plated abd all hardware is non-magnetic. Each fuse-link can be equipped with a low voltage trip-indicator which can operated a field mountable microswitch.
