Why Choose the Mersen NH1UD69V160PV High-Speed Semiconductor Fuse?
The Mersen NH1UD69V160PV is a robust NH Size 1 high-speed semiconductor fuse designed to protect sensitive power electronic components against damaging short-circuit currents. Its ultra-rapid operating characteristics help limit peak fault current and reduce the thermal energy transferred to semiconductor devices during an electrical fault.
Developed for demanding industrial power-conversion systems, the NH1UD69V160PV is suitable for protecting components such as diodes, thyristors, rectifiers, inverters and variable-speed drive assemblies. Its NH blade-contact construction provides a secure electrical connection and allows installation in compatible NH Size 1 fuse bases and switch-fuse equipment.
With a rated current of 160 A and a nominal voltage rating of 690 V AC, this Mersen fuse provides dependable current-limiting protection for industrial equipment. Its visual indication system helps maintenance engineers identify an operated fuse quickly, supporting efficient fault diagnosis and reduced equipment downtime.

Reliable Protection for Industrial Power Electronics
Power semiconductor devices can be permanently damaged within milliseconds when exposed to excessive fault current. The Mersen NH1UD69V160PV is designed to interrupt serious short circuits rapidly, limiting the peak current and I²t energy reaching connected electronic components.
Correct fuse selection should consider the circuit voltage, continuous operating current, prospective short-circuit current, duty cycle and energy-withstand capability of the protected semiconductor. A standard general-purpose NH fuse should not be used as a direct substitute unless its suitability has been confirmed by the equipment manufacturer.
Typical Applications
- Variable frequency drives and motor-control systems.
- Industrial inverters and power converters.
- Rectifier and thyristor protection circuits.
- Uninterruptible power supply systems.
- Battery chargers and DC power equipment.
- Renewable energy conversion systems.
- Industrial automation and control panels.
