Why Choose the Mersen K080394 MI6FA40V2P Semiconductor Fuse?
The Mersen K080394, catalogue reference MI6FA40V2P, is a compact and highly responsive semiconductor protection fuse designed to protect sensitive power electronic components against overcurrent and short-circuit faults. Its high-speed operating characteristic helps minimise damaging fault energy before it can affect semiconductor devices or associated equipment.
Part of the Mersen 6.3 × 32 mm FA/FB miniature fuse series, the K080394 combines fast fault interruption with a compact cartridge design. It is suitable for industrial electronic equipment where dependable semiconductor protection, limited installation space and reliable indication of fuse operation are required.
With a rated current of 2 A and a rated voltage of 400 V AC, the Mersen K080394 is designed for clip mounting in a compatible fuse holder. Its integrated striker provides a mechanical indication when the fuse operates and can activate compatible signalling or tripping accessories.

Fast Protection for Sensitive Power Electronics
Power semiconductor components can be damaged by fault currents that rise too quickly for conventional circuit protection devices. The Mersen K080394 uses a high-speed fuse element to interrupt excessive current rapidly, helping reduce the thermal and electrical stress placed on sensitive electronic components.
The compact 6.3 × 32 mm format makes the fuse suitable for installation in space-restricted control panels, power supplies and electronic assemblies. Its integrated striker also supports clear fault indication and can interact with compatible fuse holders, auxiliary contacts or signalling systems.
Typical Applications
- Semiconductor device protection.
- Power converters and rectifier equipment.
- Variable speed drives.
- Industrial power supplies.
- UPS and power conditioning systems.
- Automation and electronic control equipment.
