Why Choose the Mersen D080917 High-Speed Miniature Fuse?
The Mersen D080917, catalogue reference MI6FA40V4P, is a compact high-speed semiconductor miniature fuse designed to protect sensitive electronic components and power semiconductor devices against damaging overcurrents and short circuits. Part of Mersen’s 6.3 × 32 mm FA/FB fuse range, it provides rapid fault interruption for industrial electronics, power conversion equipment and automation systems.
Rated at 4 A and 400 V AC, the D080917 features a very fast FA operating characteristic that helps minimise the energy passed into protected equipment during a fault. This makes it suitable for safeguarding diodes, thyristors, rectifiers and other semiconductor devices that require faster protection than a conventional general-purpose fuse can provide.
The fuse features a durable ceramic body, ferrule terminals and a compact clip-mounted design for installation in compatible fuse holders. An integrated striker indication system provides a clear mechanical indication when the fuse has operated, helping maintenance personnel identify a faulted fuse quickly. Its 200 kA minimum interrupting rating supports dependable performance in demanding industrial applications.

High-Speed Protection for Sensitive Power Electronics
Semiconductor devices can be damaged by fault currents that rise too quickly for standard general-purpose fuses to interrupt effectively. The Mersen D080917 uses a high-speed FA characteristic to disconnect excessive current rapidly, helping reduce thermal and electrical stress on sensitive components.
Its low melting and clearing I²t values help limit the energy released during fault interruption. The integrated striker also supports faster maintenance by providing a clear indication after operation, while the compact clip-mounted design simplifies replacement in compatible fuse holders.
Typical Applications
- Semiconductor device protection.
- Industrial power supplies.
- Rectifiers and power converters.
- Variable speed drive control circuits.
- Industrial automation equipment.
- Electronic control panels.
- Power electronic assemblies.
