Why Choose the Mersen L214071 5 x 20 mm Medium Time-Lag Fuse?
The Mersen L214071, catalogue reference MI5SM25V1, is a compact 5 x 20 mm medium time-lag miniature fuse designed to protect electrical distribution circuits, control equipment and industrial electrical systems against damaging overcurrents. Rated at 1 A and 250 V AC, it combines dependable circuit protection with the ability to tolerate brief current surges.
As part of the established Mersen 5SM IEC miniature fuse series, the L214071 is particularly suitable for equipment where normal start-up or switching conditions may produce temporary inrush currents. Its medium time-lag characteristic helps reduce unnecessary fuse operation while still disconnecting the circuit when a sustained overload or short circuit occurs.
The fuse features a transparent glass body, nickel-plated brass contact caps and a standard 5 x 20 mm format for use with compatible clips, fuse bases and enclosed fuse holders. It complies with IEC 60127-2 Sheet 2 and offers an AC breaking capacity of 80 A.
