Why Choose the Mersen A094415 MI6FA40V1.25P Miniature Fuse?
The Mersen A094415 MI6FA40V1.25P is a compact 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 range, it combines rapid fault interruption with a space-saving 6.3 × 32 mm cartridge format.
Its FA high-speed operating characteristic helps limit the thermal energy passed through to vulnerable semiconductor components during a fault. This makes the fuse suitable for converters, rectifiers, electronic power supplies and industrial control equipment where conventional general-purpose fuses may not respond quickly enough.
Rated at 1.25 A and 400 V AC, the Mersen A094415 features a built-in striker indication system that provides a clear mechanical indication when the fuse has operated. Its ceramic body, ferrule terminals and extremely high interrupting capacity provide dependable protection in demanding electronic and industrial applications.
