Why Choose the Mersen N084422 Medium Time-Lag Fuse?
The Mersen N084422, catalogue number MI6SA25V0.4, is a compact semiconductor miniature cartridge fuse designed to protect sensitive electronic components and control apparatus against damaging overcurrents. Its medium time-lag SA characteristic allows brief current surges while providing dependable interruption of sustained overloads and short circuits.
Rated at 0.4 A and 250 V AC, the N084422 is suitable for low-current electronic and industrial control circuits. Its standard 6.3 × 32 mm cylindrical format enables straightforward installation in compatible clip-mounted fuse holders.
As part of Mersen’s semiconductor miniature fuse range, the N084422 combines compact dimensions with a very high breaking capacity. This makes it particularly useful in applications where equipment may experience temporary inrush currents during start-up but still requires reliable protection against persistent electrical faults.

Reliable Protection with Inrush Current Tolerance
Electronic equipment can draw a temporary surge of current when power is first applied. The medium time-lag characteristic of the Mersen N084422 allows these brief, harmless inrush currents to pass without unnecessary fuse operation while still responding to sustained overloads and short-circuit conditions.
This operating behaviour makes the fuse suitable for control apparatus, power supplies and electronic assemblies that require a balance between surge tolerance and dependable semiconductor protection. Its compact cartridge format also makes it ideal for equipment where installation space is restricted.
Typical Applications
- Sensitive electronic component protection.
- Industrial control apparatus.
- Automation and monitoring equipment.
- Electronic power supplies.
- Test and measurement instruments.
- OEM electrical and electronic assemblies.
