MERSEN FUSE 5SM 1,25A MITTELTR. MI5SM25V1,25

Why Choose the Mersen T214584 5SM Miniature Fuse?

The Mersen T214584 is a dependable medium time-lag miniature cartridge fuse developed to protect electrical distribution circuits and industrial equipment against sustained overloads and short-circuit conditions. Part of the Mersen 5SM IEC miniature fuse series, it combines reliable fault protection with the ability to tolerate brief current surges during normal equipment start-up.

With a rated current of 1.25 A and a rated voltage of 250 V AC, the T214584 is suitable for control equipment, instrumentation, power supplies and other industrial electrical applications. Its medium time-lag characteristic helps prevent unnecessary fuse operation when transformers, capacitors or other loads produce temporary inrush currents.

The fuse uses the standard 5 × 20 mm cartridge format, allowing straightforward installation into compatible miniature fuse holders. Its compact size and controlled operating response make it a practical circuit protection solution for equipment manufacturers, panel builders and maintenance engineers.
