MERSEN FUSE 250V SA 0,63 A 5.20 MI5SA25V0,63

Why Choose the Mersen F084116 Medium Time-Lag Miniature Fuse?

The Mersen F084116, catalogue reference MI5SA25V0.63, is a compact medium time-lag miniature semiconductor fuse designed to protect sensitive electronic components, semiconductor devices and control equipment against damaging overcurrents. It forms part of Mersen’s 5 × 20 mm SA/SB miniature fuse range, developed for circuits that must withstand temporary current surges without compromising dependable fault protection.

With a rated current of 0.63 A and a rated voltage of 250 V AC, the F084116 is suitable for industrial electronics, instrumentation, control apparatus and power supply circuits. Its SA medium time-lag characteristic allows brief inrush currents and normal transient loads to pass while responding to sustained overloads and short-circuit conditions.

The fuse is manufactured in a standard 5 × 20 mm cylindrical cartridge format and is designed for clip mounting in a compatible fuse holder. This compact construction enables straightforward installation and replacement within control panels, electronic equipment and other space-restricted electrical assemblies.
