Why Choose the Mersen NH2GS69V160PV High-Speed Semiconductor Fuse?
The Mersen NH2GS69V160PV is a high-performance NH Size 2 high-speed semiconductor fuse link designed to protect sensitive power electronic equipment against overloads and damaging short-circuit currents. As part of the established Mersen Protistor® range, it offers fast current limitation for semiconductor devices used in industrial drives, converters, rectifiers and power-control systems.
Power semiconductors such as IGBTs, thyristors and diodes can be damaged rapidly when excessive current flows through a circuit. The NH2GS69V160PV features a gS utilisation category, providing full-range protection with operating characteristics developed for semiconductor devices and their associated conductors and equipment.
With a rated current of 160 A, a rated voltage of 690 V AC and a robust NH Size 2 blade-contact format, this fuse is suitable for demanding industrial power-conversion applications. Its standard NH construction enables straightforward installation in compatible fuse bases, fuse holders and switch-disconnector assemblies.

Reliable Protection for Power Electronic Equipment
High-speed semiconductor fuses are engineered to interrupt fault currents more rapidly than conventional industrial fuse links. Their current-limiting characteristics reduce the thermal and electrical energy reaching sensitive semiconductor components, helping prevent extensive equipment damage and costly production downtime.
The Mersen NH2GS69V160PV combines fast semiconductor protection with a full-range gS operating characteristic. This allows the fuse to protect against both lower-level sustained overcurrents and severe short-circuit faults when correctly selected and coordinated within the electrical system.
Typical Applications
- Variable frequency drives and industrial motor drives.
- Power converters and inverter systems.
- Industrial rectifiers and power supplies.
- Uninterruptible power supply systems.
- Soft starters and motor-control equipment.
- Protection of IGBTs, thyristors, diodes and semiconductor modules.
