Why Choose the Mersen B084411 MI6SA25V5 Miniature Fuse?

The Mersen B084411 MI6SA25V5 is a compact 5 A semiconductor miniature fuse designed to provide reliable overcurrent protection for sensitive electronic components, semiconductor devices and industrial control apparatus. Part of Mersen’s MI6SA 125–250 V fuse series, it combines dependable circuit protection with a compact 6.3 × 32 mm cartridge format.

Its medium time-lag SA operating characteristic allows the fuse to withstand brief inrush currents and short-duration surges without unnecessary operation. This makes it particularly suitable for electronic equipment and control circuits that experience temporary current peaks during start-up while still requiring effective protection against sustained overcurrents.

Rated at 5 A and 250 V AC, the Mersen B084411 is designed for clip mounting in a compatible miniature fuse holder. Its high-quality construction and very high breaking capacity provide consistent performance in industrial automation, electronic control and OEM equipment applications.

Key Advantages

  • Compact 6.3 × 32 mm semiconductor miniature fuse.
  • 5 A rated current for electronic and control circuits.
  • 250 V AC rated voltage.
  • Medium time-lag characteristic tolerates brief inrush currents.
  • Very high breaking capacity for dependable fault interruption.
  • Helps protect sensitive semiconductor devices and control apparatus.

Key Features

  • Mersen MI6SA semiconductor miniature fuse series.
  • 5 A rated current.
  • 250 V AC rated voltage.
  • Medium time-lag SA operating characteristic.
  • Standard 6.3 × 32 mm cartridge size.
  • Clip-mounted installation in a compatible fuse holder.
  • Designed for circuits subject to temporary current surges.
  • Suitable for semiconductor devices and electronic control equipment.

Reliable Protection for Circuits with Inrush Current

Electronic components and control devices can be damaged when excessive current creates thermal stress beyond their operating limits. The Mersen B084411 helps protect connected equipment by interrupting sustained overcurrents and short-circuit faults before damaging energy reaches sensitive components.

The medium time-lag characteristic allows harmless start-up surges and temporary current peaks to pass without immediately operating the fuse. This helps reduce nuisance fuse replacement while maintaining dependable protection against genuine electrical faults.

Typical Applications

  • Semiconductor device protection.
  • Industrial electronic control equipment.
  • Automation and instrumentation circuits.
  • Electronic power supplies.
  • Circuits with temporary inrush currents.
  • OEM electronic and electrical assemblies.
