MERSEN FUSE 250V M 2,5 A 5.25 MI5M25V2,5P

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.
