Why Choose the Mersen NH0UD69V200PV Protistor® High Speed Fuse?
The Mersen NH0UD69V200PV is a high-performance Protistor® high speed semiconductor fuse designed to protect sensitive power electronic components against damaging short-circuit currents. Its ultra-fast operating characteristics help safeguard IGBTs, thyristors, diodes and rectifier assemblies used in demanding industrial power conversion systems.
Manufactured in the standard NH Size 0 format, this fuse combines reliable current limitation with low energy let-through performance. Its robust square-body construction and blade connections make it suitable for compatible NH fuse bases, switch disconnectors and industrial electrical protection assemblies.
With a rated current of 200 A, a 690 V AC IEC voltage rating and an aR utilisation category, the NH0UD69V200PV is ideal for variable frequency drives, industrial inverters, power converters and other semiconductor-based equipment requiring rapid fault interruption.

Reliable Protection for Power Electronic Equipment
Semiconductor devices can sustain permanent damage when exposed to high short-circuit currents, even for extremely brief periods. The Mersen NH0UD69V200PV is engineered to interrupt these faults rapidly, limiting peak current and reducing the thermal energy transferred to protected components.
The fuse’s aR operating characteristic is specifically intended for short-circuit protection of semiconductor devices. It should be used as part of a properly coordinated protection system, with overload protection provided separately where required by the equipment design.
Typical Applications
- Variable frequency drives and variable speed drives.
- Industrial power converters and rectifiers.
- Solar and renewable energy inverters.
- Uninterruptible power supply systems.
- Industrial motor control equipment.
- Battery energy storage power converters.
- Welding and electrolysis equipment.
- Semiconductor protection circuits.
