Why Choose the Mersen NH00UD69V20PV High-Speed Fuse?
The Mersen NH00UD69V20PV is a compact NH00 high-speed fuse link designed to protect sensitive power semiconductor equipment against damaging overcurrents and short circuits. Manufactured by Mersen, a specialist in electrical protection technology, this fuse is suitable for demanding industrial power-conversion and electronic equipment.
High-speed fuses operate more rapidly than conventional industrial fuse links, helping to limit the peak current and energy transmitted during an electrical fault. This fast response is particularly important when protecting semiconductor devices whose internal components can be damaged before a standard fuse has time to disconnect the circuit.
With a rated current of 20 A and a voltage designation of 690 V, the NH00UD69V20PV provides dependable protection within compatible installations. Its standard NH00 blade-contact format supports secure installation in an appropriate NH fuse base, switch disconnector or fuse holder.

Rapid Protection for Sensitive Power Electronics
Power semiconductors used in drives, rectifiers, inverters and industrial power supplies can be highly sensitive to excessive current. A high-speed fuse limits both the magnitude and duration of fault current, reducing the thermal and mechanical stress placed on protected components.
The Mersen NH00UD69V20PV is designed for use where rapid circuit interruption is required. Correct fuse selection should consider the circuit voltage, continuous operating current, prospective fault current, time-current characteristics and the energy withstand capability of the protected semiconductor device.
Typical Applications
- Variable-speed drives and motor-control equipment.
- Industrial rectifiers and converters.
- Uninterruptible power supplies.
- Power semiconductor protection.
- Industrial inverters and power supplies.
- Automation and electrical control panels.
