Why Choose the Mersen N084353 High-Speed Fuse?
The Mersen N084353, catalogue number MI6FA40V0.25, is a compact high-speed miniature cartridge fuse designed to protect sensitive semiconductor devices and electronic components against damaging overcurrents and short circuits. Its very fast-acting FA characteristic helps interrupt electrical faults rapidly, limiting the energy passed to protected equipment.
Rated at 0.25 A and 400 V AC, the N084353 is suitable for low-current electronic circuits where conventional general-purpose fuses may not operate quickly enough. Its standard 6.3 × 32 mm cylindrical format enables straightforward installation in compatible clip-mounted fuse holders.
As part of Mersen’s semiconductor miniature fuse range, the N084353 combines compact dimensions with dependable high-speed protection. It is well suited to industrial automation equipment, test instruments, power electronics and OEM assemblies containing sensitive electronic components.
