Why Choose the Mersen Q084355 MI6FA40V1 High Speed Miniature Fuse?
The Mersen Q084355, catalogue reference MI6FA40V1, is a compact high speed semiconductor miniature fuse designed to protect sensitive electronic components, semiconductor devices and industrial control equipment against damaging overcurrents and short circuits. It forms part of Mersen's dependable MI6 FA/FB 400 V miniature fuse range.
Rated at 1 A and 400 V AC, the Q084355 features a very fast-acting FA characteristic. This rapid response helps restrict the electrical and thermal energy transferred to protected semiconductor components during a fault, reducing the likelihood of equipment damage and unplanned downtime.
The fuse uses a compact 6.3 × 32 mm cylindrical cartridge format designed for clip mounting in a compatible miniature fuse holder. Its high breaking capacity, rapid operating characteristic and space-saving construction make it suitable for power supplies, industrial electronics, measuring equipment, automation systems and OEM assemblies.

Rapid Protection for Sensitive Electronic Components
Semiconductor devices may be damaged by overcurrents that last for only a short period. High speed fuses are designed to respond more rapidly than standard general-purpose fuses, helping reduce the thermal and electrical stress applied to protected components.
The Mersen Q084355 combines a very fast FA operating characteristic with a compact cartridge construction. This makes it suitable for industrial electronics and power-electronic assemblies where rapid fault clearance, reliable interruption and limited installation space are important.
Typical Applications
- Semiconductor protection circuits.
- Industrial electronic equipment.
- Electronic power supplies.
- Automation and control systems.
- Measuring and test equipment.
- Power-electronic assemblies.
- Control and signalling apparatus.
- OEM electronic machinery.
