Why Choose the Mersen R084356 High-Speed Semiconductor Fuse?
The Mersen R084356, catalogue reference MI6FA40V1.25, is a compact high-speed semiconductor miniature fuse designed to protect sensitive electronic components against damaging overcurrents and short circuits. It forms part of Mersen's 6.3 × 32 mm FA/FB fuse range for industrial electronics and power control applications.
Its FA very fast-acting characteristic enables rapid fault interruption, helping limit the thermal and electrical energy transferred to semiconductor devices. This makes the R084356 suitable for protecting diodes, thyristors, rectifiers, converters and other electronic components with limited overcurrent withstand capability.
With a rated current of 1.25 A and a rated voltage of 400 V AC, the R084356 provides dependable protection for low-current industrial electronic circuits. Its standard 6.3 × 32 mm cylindrical format is designed for clip mounting in a compatible fuse holder, allowing straightforward installation and replacement.
