Why Choose the Mersen B084365 MI6FA40V10 Miniature Fuse?

The Mersen B084365 MI6FA40V10 is a compact 10 A high-speed semiconductor miniature fuse designed to protect sensitive electronic components and power semiconductor devices against damaging overcurrents and short circuits. Part of Mersen’s MI6FA 400 V fuse series, it delivers very fast fault interruption in a compact 6.3 × 32 mm ceramic cartridge format.

Its high-speed FA operating characteristic helps limit the thermal energy passed through to vulnerable semiconductor components during an electrical fault. This makes the fuse particularly suitable for converters, rectifiers, power supplies and industrial control equipment where conventional general-purpose fuses may not respond quickly enough.

Rated at 10 A and 400 V AC, the Mersen B084365 provides a very high 150 kA minimum interrupting rating. Its ceramic body, ferrule terminals and clip-mounted design provide dependable performance in demanding power electronic, automation and OEM applications.
