Why Choose the Mersen B090805 Miniature Fuse?

The Mersen B090805, catalogue reference MI6HA25T25V8, is a compact semiconductor miniature fuse designed to protect sensitive electronic components, control equipment and low-voltage electrical circuits against damaging overcurrent conditions. It forms part of Mersen’s 6.3 × 32 mm HA 25 miniature fuse series.

This fuse features a super-slow time-delay characteristic, also identified as a TT characteristic. It can tolerate temporary current surges and equipment start-up currents without unnecessary operation, while still providing dependable circuit protection when a sustained overcurrent occurs.

With a rated current of 8 A and a rated AC voltage of 220 V, the Mersen B090805 is suitable for use in compatible semiconductor equipment, electronic control systems and industrial apparatus. Its standard cylindrical dimensions and clip-mounting design enable straightforward installation into suitable fuse clips and holders.

Key Advantages

  • Compact 6.3 × 32 mm miniature fuse for electronic protection.
  • 8 A current rating for compatible control and semiconductor circuits.
  • 220 V AC rated voltage.
  • Super-slow TT time-delay characteristic withstands temporary current surges.
  • Helps protect sensitive electronic components from sustained overcurrents.
  • Clip-mounted construction supports convenient installation and replacement.

Key Features

  • Mersen HA 25 semiconductor miniature fuse series.
  • Manufacturer item number: B090805.
  • Catalogue number: MI6HA25T25V8.
  • Rated current: 8 A.
  • Rated voltage: 220 V AC.
  • Operating characteristic: Super slow (TT).
  • Fuse dimensions: 6.3 × 32 mm.
  • Designed for installation using compatible fuse clips.

Dependable Protection for Sensitive Electronic Circuits

Miniature fuses protect electrical and electronic equipment by interrupting the circuit when current remains above the fuse’s designed operating threshold. This helps prevent excessive heat and electrical damage from affecting sensitive components, wiring and connected apparatus.

The super-slow operating characteristic of the Mersen B090805 makes it particularly useful in circuits that experience temporary inrush currents during normal operation. The fuse allows these brief surges to pass while remaining capable of disconnecting sustained overloads in properly coordinated applications.

Typical Applications

  • Semiconductor equipment and electronic assemblies.
  • Industrial control and automation apparatus.
  • Electronic power supply circuits.
  • Control boards and sensitive electronic components.
  • Instrumentation and monitoring equipment.
  • Low-voltage circuits with temporary inrush currents.
