Why Choose the Mersen Q079019 MI5M25V2.5P Miniature Fuse with Striker?

The Mersen Q079019, catalogue reference MI5M25V2.5P, is a compact 5 × 25 mm miniature cartridge fuse designed to provide reliable overcurrent protection for industrial controls, electronic equipment and auxiliary electrical circuits. Rated at 2.5 A and 250 V AC, it is suitable for applications requiring dependable protection within a compact fuse format.

This fuse features a medium time-lag operating characteristic, allowing it to withstand brief start-up and inrush currents without unnecessary operation. It will still disconnect sustained overloads and short-circuit faults, making it suitable for circuits containing transformers, relays, contactors and power supplies.

An integrated mechanical striker provides visible indication when the fuse has operated and can interact with compatible signalling fuse holders. Its ceramic cylindrical body and very high breaking capacity support reliable fault interruption in demanding industrial and electronic installations.

Key Advantages

  • Compact 5 × 25 mm miniature fuse for space-conscious installations.
  • 2.5 A current rating for low-power control and electronic circuits.
  • 250 V AC voltage rating suitable for industrial equipment.
  • Medium time-lag characteristic accommodates temporary inrush currents.
  • Integrated striker assists fuse-status indication and fault identification.
  • Very high breaking capacity provides dependable fault interruption.

Key Features

  • Mersen MI5 M miniature fuse series.
  • Catalogue reference: MI5M25V2.5P.
  • Manufacturer part number: Q079019.
  • Rated current: 2.5 A.
  • Rated voltage: 250 V AC.
  • Medium time-lag M operating characteristic.
  • Integrated mechanical striker.
  • Ceramic cylindrical cartridge construction.
  • Designed for compatible clip-mounted fuse holders.
  • UL recognised fuse range.

Reliable Protection for Control and Electronic Circuits

Medium time-lag fuses are designed to tolerate brief current surges that occur when transformers, power supplies and electromagnetic devices are energised. This helps reduce nuisance fuse operation while retaining effective protection against persistent overload and short-circuit conditions.

The Mersen Q079019 combines controlled time-delay performance with a striker indication mechanism. This makes it particularly useful in industrial control systems where rapid identification of an operated fuse can help reduce maintenance time and equipment downtime.

Typical Applications

  • Industrial control panels.
  • Transformer primary and secondary circuits.
  • Relay and contactor control circuits.
  • Electronic power supplies.
  • Automation equipment.
  • Instrumentation and monitoring systems.
  • OEM machinery and electrical equipment.
