Why Choose the Mersen K081038 MI6FA12.5V30P Semiconductor Fuse?
The Mersen K081038, catalogue reference MI6FA12.5V30P, is a compact high-speed semiconductor protection fuse designed to protect sensitive electronic components, semiconductor devices and control equipment against overcurrent and short-circuit faults. Its very fast-acting FA characteristic helps limit damaging fault energy before it can affect connected equipment.
Part of the Mersen 6.3 × 32 mm FA miniature fuse series, the K081038 combines a high current rating with a compact cylindrical cartridge format. It is particularly suitable for power electronic equipment where rapid fault interruption, dependable performance and limited installation space are important considerations.
With a rated current of 30 A and a rated voltage of 125 V AC, the Mersen K081038 is designed for clip mounting in a compatible fuse holder. Its integrated striker provides mechanical indication when the fuse operates and can be used with suitable signalling or tripping accessories.

Fast Protection for Sensitive Power Electronics
Semiconductor devices can be damaged by fault currents that rise more rapidly than conventional circuit protection devices can respond. The Mersen K081038 uses a very fast-acting fuse element to interrupt excessive current quickly, helping reduce thermal stress and damaging energy within electronic circuits.
Its compact 6.3 × 32 mm design makes it suitable for power supplies, converters, control equipment and other assemblies where space is limited. The integrated striker can also provide local indication or operate compatible auxiliary signalling equipment after the fuse has interrupted a fault.
Typical Applications
- Semiconductor device protection.
- Industrial power electronic equipment.
- Power supplies and converter systems.
- Measuring and control apparatus.
- Automation and electronic control panels.
- Rectifier and switching circuits.
