Why Choose the Mersen NH0UD69V80PV High-Speed Fuse?
The Mersen NH0UD69V80PV is a compact NH size 0 high-speed fuse link designed to protect power semiconductor devices and industrial power electronic equipment against damaging short-circuit currents. Manufactured by Mersen, it provides rapid fault interruption and effective current limitation for demanding electrical protection applications.
Its fast operating characteristics help minimise peak fault current and reduce the let-through energy reaching sensitive downstream components. This makes the NH0UD69V80PV suitable for circuits containing power semiconductors such as diodes, thyristors, rectifiers and insulated-gate bipolar transistors.
With a rated current of 80 A and a rated voltage of up to 690 V AC, the NH0UD69V80PV is suitable for industrial drives, power converters, inverters and automation equipment. Its standard NH0 blade-contact format enables secure installation in compatible NH fuse bases and switch-disconnector assemblies.

Reliable Protection for Power Semiconductor Equipment
High-speed fuse links such as the Mersen NH0UD69V80PV are designed to interrupt severe fault currents more rapidly than conventional general-purpose fuse links. Their fast response limits the electrical energy that reaches sensitive downstream components during a short circuit.
This current-limiting behaviour is particularly important in variable frequency drives, rectifiers, inverters and other power electronic systems where semiconductor devices can be damaged by brief overcurrent events. Correct fuse selection helps improve equipment reliability, minimise unplanned downtime and reduce the risk of costly component failure.
Typical Applications
- Variable frequency drives and industrial motor controllers.
- Power inverters and converter systems.
- Industrial rectifiers and semiconductor assemblies.
- Uninterruptible power supplies.
- Automation panels and machine control equipment.
- Industrial power distribution assemblies.
