Overview

Mersen’s Miniature Fuse (SKU: Y084408) is a 6.3x32mm, 250V, 2.5A fuse with medium time-lag (SA) characteristics, designed for precise overcurrent protection in sensitive electronic circuits. The SA time-lag allows brief surges—common in semiconductor devices and control systems—while interrupting sustained overcurrents to prevent damage. These fuses are clip-mounted for direct integration into compact control panels, power supplies, and industrial automation systems. With a high breaking capacity, they safely handle inrush currents typical in motor startups, transformers, and capacitive loads without nuisance tripping. Available with or without a trip indicator for visual fault detection, these fuses provide a balance of responsiveness and durability. Their miniature form factor (6.3x32mm) ensures compatibility with standard fuse holders and clips, making them a versatile choice for applications requiring 125V–250V protection. Ideal for use in power distribution units, test equipment, and control circuits where space constraints and reliability are critical.
  • Compact 6.3x32mm size for space-constrained applications
  • Medium time-lag (SA) design allows brief surges while protecting against sustained overcurrent
  • 250V rating with 2.5A current for sensitive electronic and control circuits
  • Clip mounting for direct integration into standard fuse holders
  • Available with or without trip indicator for fault visibility
