Why Choose the Mersen X084407 Semiconductor Miniature Fuse?
The Mersen X084407, catalogue number MI6SA25V2, is a compact and dependable semiconductor miniature fuse designed to protect sensitive electronic components, semiconductor devices and industrial control equipment against damaging overcurrents. It forms part of Mersen’s 6.3 × 32 mm SA miniature fuse range for applications that require reliable circuit protection with tolerance for brief current surges.
Its medium time-lag SA characteristic allows the fuse to withstand short-duration inrush currents while still providing effective protection against sustained overloads and short circuits. This operating behaviour makes the X084407 suitable for electronic power supplies, control apparatus, converters and other equipment where momentary current peaks are expected during normal operation.
Rated at 2 A and 250 V AC, the Mersen X084407 combines a robust ceramic cartridge body with a very high 200 kA minimum interrupting rating. Its ferrule terminals and clip-mounted format provide straightforward installation in compatible fuse holders within electrical panels, electronic assemblies and industrial equipment.
