Why Choose the Mersen NH0UD69V100PV Protistor® High-Speed Fuse?
The Mersen NH0UD69V100PV is an NH size 0 high-speed semiconductor protection fuse designed for rapid interruption of short-circuit currents in industrial power-electronic equipment. Part of the established Mersen Protistor® range, it helps protect sensitive semiconductor components such as IGBTs, thyristors, diodes and rectifier assemblies.
Its current-limiting construction helps reduce the damaging energy passed to connected equipment during an electrical fault. The NH blade format enables installation in compatible fuse bases and switch-disconnector assemblies, while the compact square-body design supports reliable operation within industrial control panels and power-conversion systems.
With a rated current of 100 A and a voltage designation of 690 V AC, the NH0UD69V100PV is suitable for drives, converters, inverters, UPS equipment and other applications requiring dependable high-speed semiconductor protection.

Reliable Protection for Power Electronics
High-speed fuses operate more rapidly than conventional industrial fuse links, limiting the fault current and thermal energy that can reach sensitive semiconductor devices. This rapid response can help prevent extensive equipment damage, reduce maintenance requirements and minimise unplanned production downtime.
The Mersen NH0UD69V100PV is particularly suited to circuits containing power semiconductors that require dedicated short-circuit protection. Its standard NH construction also simplifies integration into compatible industrial distribution and control equipment.
Typical Applications
- Variable frequency drives and motor-control systems.
- Industrial power converters and rectifiers.
- Inverter and power-supply equipment.
- UPS and backup power systems.
- Industrial automation panels.
- Protection of IGBTs, thyristors and power diodes.
