Why Choose the Mersen NH00UD69V63PV High-Speed Semiconductor Fuse?
The Mersen NH00UD69V63PV is a Protistor® NH high-speed semiconductor fuse intended to protect sensitive power electronic equipment against damaging short-circuit currents. Its fast operating performance helps limit the thermal and electrical energy transferred to semiconductor devices during a fault.
The product reference identifies a nominal 63 A current rating, 690 V AC voltage class and NH Size 00 construction. This compact industrial format is suitable for compatible NH fuse bases, fuse-switch disconnectors and electrical assemblies used in power conversion and automation equipment.
Designed for semiconductor protection, the NH00UD69V63PV can help safeguard devices such as IGBTs, thyristors, diodes and rectifier assemblies. Its low let-through energy supports reliable operation in industrial drives, inverters, UPS systems and other applications containing sensitive power electronics.

Reliable Protection for Power Electronic Equipment
Semiconductor devices can be damaged by fault energy before a conventional industrial fuse operates. High-speed semiconductor fuses are designed to clear short-circuit currents rapidly, helping to minimise thermal stress and reduce the risk of extensive damage to power electronic assemblies.
For safe replacement, the Mersen NH00UD69V63PV should be matched using its complete manufacturer reference. The current rating, voltage rating, operating characteristic, breaking capacity, dimensions and contact arrangement must all comply with the protected equipment’s specification.
Typical Applications
- Variable frequency drives.
- Industrial inverters.
- Uninterruptible power supply systems.
- Power converters.
- Industrial rectifier assemblies.
- Motor-control equipment.
- Renewable energy conversion systems.
- OEM industrial machinery.
