Why Choose the Mersen T079022 MI5M25V6.3P Miniature Fuse?

The Mersen T079022 (MI5M25V6.3P) is a compact 5 × 25 mm miniature cartridge fuse designed to provide dependable overcurrent and short-circuit protection for electrical and electronic equipment. Manufactured by Mersen, it is suitable for industrial controls, automation equipment, instrumentation and OEM assemblies requiring reliable circuit protection.

With a rated current of 6.3 A and a rated voltage of 250 V AC, the T079022 helps protect wiring and components against sustained overloads and fault currents. Its medium time-lag operating characteristic allows brief inrush currents to pass without unnecessary fuse operation, making it suitable for circuits containing transformers, motors, power supplies or capacitive loads.

The fuse features a robust ceramic cartridge body and an integrated striker indicator. This striker provides mechanical fuse-operation indication and may activate a compatible microswitch or signalling device, helping maintenance personnel identify and diagnose circuit faults efficiently.
