Why Choose the Mersen Q098040 Semiconductor Fuse?
The Mersen Q098040 is an industrial fuse developed for the protection of power-electronic equipment and sensitive semiconductor circuits. Mersen high-speed fuse technology is commonly used where rapid fault interruption and effective current limitation are required to protect valuable components such as diodes, thyristors, rectifiers and power transistors.
By limiting the peak current and thermal energy released during a fault, the Q098040 can help reduce damage to protected equipment, improve system reliability and minimise costly production downtime. It is suitable for maintenance, repair and replacement applications where the original equipment manufacturer specifies Mersen part number Q098040.
The product reference indicates a nominal current rating of 40 A. However, complete electrical and dimensional data for this legacy or specialist Mersen reference is not consistently available in current public catalogues. The voltage rating, operating class, breaking capacity, dimensions and terminal configuration should therefore be confirmed from the original fuse label, equipment documentation or an authorised Mersen datasheet before installation.
Key Advantages

- Fast current-limiting operation helps reduce damaging fault energy.
- Supports reliable protection of semiconductor-based equipment.
- Suitable as a replacement where Q098040 is the specified part number.
- Manufactured by Mersen, a specialist in industrial electrical protection.

Reliable Protection for Power-Electronic Equipment
Semiconductor devices can be permanently damaged by fault energy before a conventional general-purpose fuse has time to operate. High-speed fuses are engineered to respond rapidly, limiting both the peak fault current and the total energy transmitted to the protected components.
For replacement applications, the complete fuse specification must match the original component. Current rating alone is not sufficient: voltage rating, utilisation category, breaking capacity, dimensions, terminal arrangement and time-current performance must also be compatible with the equipment.
Typical Applications
- Industrial power converters.
- Rectifier and inverter assemblies.
- Variable frequency drives.
- Motor-control equipment.
- Uninterruptible power supply systems.
- Industrial automation and OEM machinery.
