Approvals & Standards

  • UL Recognized Component File E60314
  • DC Tested to UL248-1 (1-600A)

Key features & benefits

Mersen Form 600 fuses are the original current-limiting fuses, predating all the standards. Their 500V DC rating (through 600A) is a useful feature for special fusing applications. Form 600 fuses provide a high degree of current limitation in AC and DC applications. Types 1 and 3 are dimensionally interchangeable with Class H and K fuses. Types 4 and 5 have unique rejection dimensions and are not interchangeable.
