MERSEN FUSE 5SM 200MA MITTELTR. MI5SM25V0,2

Why Choose the Mersen T201773 5SM Miniature Fuse?

The Mersen T201773 is a compact and reliable medium time-lag miniature cartridge fuse designed 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 provides dependable circuit protection while tolerating brief inrush currents that may occur during normal equipment start-up.

With a rated current of 0.2 A and a rated voltage of 250 V AC, the T201773 is suitable for sensitive low-current applications found in control equipment, instrumentation, power supplies and industrial automation systems. Its medium time-lag characteristic helps prevent nuisance operation during short-duration current surges while ensuring the circuit is disconnected when a persistent fault occurs.

The fuse uses the widely adopted 5 × 20 mm cartridge format, enabling straightforward installation into compatible miniature fuse holders. Its compact construction and dependable electrical performance make it a practical choice for original equipment manufacturers, panel builders and maintenance engineers.
