Approvals & Standards

  • IEC 60269-4 Compliance in AC and DC voltage
  • UL/CSA Recognized E76491 in AC and DC voltage
  • CCC GB 1539.4

Key features & benefits

The 690/760V Protistor® SC Series is a specific range to offer cost effective protection without concession on performance for
power conversion equipment. These fuses have been engineered to provide protection for all semiconductors: diodes, thyristors and
IGBT devices. They are assembled with bimetal silver and copper elements embedded in solidified sand, which helps control arcing
characteristics for a lower I²t and high interrupting rating level.
Contact surfaces are tin plated to get an optimized interface with the best quality/price ratio.
This SC Series has been conceived and specially optimized to match integrators’ and equipment manufaturers’ main requirements while
offering competitive prices.
