Why Choose the Mersen X093285 High-Speed Miniature Fuse?
The Mersen X093285, catalogue number MI6FA69V0.315, is a compact and highly reliable 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 fuse range, developed for applications requiring rapid fault interruption and dependable semiconductor protection.
Its very fast-acting FA characteristic helps minimise the electrical and thermal energy transferred to vulnerable semiconductor devices during a fault. This makes the X093285 particularly suitable for protecting diodes, thyristors, converters, rectifiers and associated electronic circuitry where a conventional general-purpose fuse may not respond quickly enough.
Rated at 0.315 A and 690 V AC, the Mersen X093285 combines a robust ceramic cartridge body with a 30 kA minimum interrupting rating. Its ferrule terminals and clip-mounted format allow straightforward installation in compatible fuse holders within industrial control panels, electronic equipment and power conversion systems.
