Why Choose the Mersen X093285 High-Speed Miniature Fuse?

The Mersen X093285, catalogue number MI6FA69V0.315, is a compact and highly reliable high-speed semiconductor miniature fuse designed to protect sensitive electronic components against damaging overcurrents and short circuits. It forms part of Mersen’s 6.3 × 32 mm FA fuse range, developed for applications requiring rapid fault interruption and dependable semiconductor protection.

Its very fast-acting FA characteristic helps minimise the electrical and thermal energy transferred to vulnerable semiconductor devices during a fault. This makes the X093285 particularly suitable for protecting diodes, thyristors, converters, rectifiers and associated electronic circuitry where a conventional general-purpose fuse may not respond quickly enough.

Rated at 0.315 A and 690 V AC, the Mersen X093285 combines a robust ceramic cartridge body with a 30 kA minimum interrupting rating. Its ferrule terminals and clip-mounted format allow straightforward installation in compatible fuse holders within industrial control panels, electronic equipment and power conversion systems.

Key Advantages

  • Very fast-acting FA fuse characteristic for sensitive semiconductor protection.
  • 0.315 A current rating for low-current electronic circuits.
  • 690 V AC rated voltage for higher-voltage applications.
  • 30 kA minimum interrupting rating for dependable fault clearance.
  • Low I²t values help minimise damaging energy passed to protected components.
  • Compact 6.3 × 32 mm ceramic cartridge construction.

  • 0.1 A²s clearing I²t at rated voltage.
  • Ceramic cartridge body with ferrule terminals.
  • Clip-mounted 6.3 × 32 mm fuse format.

Fast Protection for Sensitive Electronic Components

Semiconductor components can be damaged by fault currents within a very short period. High-speed fuses such as the Mersen X093285 are designed to operate rapidly and restrict the amount of energy transferred into the protected circuit, helping prevent costly damage to sensitive power electronic devices.

The ceramic body and high interrupting capacity provide dependable containment during short-circuit conditions. Its compact cartridge dimensions make it suitable for space-limited control panels, converters, power supplies and industrial automation equipment requiring high-voltage semiconductor protection.

Typical Applications

  • Semiconductor converters and power electronic equipment.
  • Diode, thyristor and rectifier protection.
  • Industrial control and automation systems.
  • Electronic power supplies and converters.
  • Measurement and instrumentation equipment.
  • High-voltage control circuits requiring rapid fault interruption.
