Why Choose the Mersen NH000GS69V25PV High-Speed Semiconductor Fuse?
The Mersen NH000GS69V25PV is a compact Protistor® NH Size 000 high-speed semiconductor fuse designed to protect sensitive power-electronic equipment against overloads and short-circuit faults. Its gS full-range operating characteristic combines semiconductor protection with cable and installation protection, making it suitable for circuits requiring broader protection than an aR fuse can provide.
Rated at 25 A with a nominal voltage class of 690 V AC, the NH000GS69V25PV provides rapid fault interruption and low energy let-through. This helps reduce thermal and electrical stress on IGBTs, thyristors, diodes and other semiconductor components used in industrial power-conversion equipment.
Its space-efficient NH000 square-body format, blade contacts and visual indication support straightforward integration and maintenance in compatible fuse bases, switch-fuse units and industrial control panels.
Key Advantages
- gS full-range protection for semiconductor devices, conductors and associated equipment.
- 25 A rated current for lower-current power-electronic circuits.
- 690 V AC voltage class for demanding industrial installations.
- Fast fault interruption with low energy let-through.
- Compact NH Size 000 construction saves panel space.
- Visual indication supports faster fault identification and maintenance.
Key Features
- Mersen Protistor® high-speed fuse technology.
- 25 A nominal current rating.
- 690 V AC nominal voltage class.
- gS utilisation category.
- NH Size 000 square-body format.
- Knife-blade contact arrangement.
- Designed for low I²t and rapid fault clearing.
- Suitable for coordinated semiconductor and conductor protection.
Full-Range Protection for Power-Electronic Circuits
Unlike an aR fuse, which is intended primarily for short-circuit protection, a gS fuse provides full-range protection. It can respond to both overload and short-circuit conditions while maintaining the fast operating performance required to protect semiconductor devices.
This combination makes the Mersen NH000GS69V25PV suitable for installations where engineers need coordinated protection for power semiconductors, connecting conductors and associated electrical equipment in a compact NH fuse format.
Typical Applications
- Variable-frequency and variable-speed drives.
- Industrial motor-control equipment.
- Power converters and rectifiers.
- Inverters and power supplies.
- UPS and battery-conversion systems.
- Renewable-energy conversion equipment.
- Industrial automation panels.
- Semiconductor-controlled heating systems.

Frequently Asked Questions
What is the Mersen NH000GS69V25PV used for?
It is used to protect power semiconductors, conductors and associated equipment against overload and short-circuit faults in industrial power-electronic systems.
What is the current rating of the NH000GS69V25PV?
The fuse has a nominal current rating of 25 A.
What does the gS classification mean?
The gS classification identifies a full-range high-speed fuse designed to protect semiconductor devices while also providing overload and short-circuit protection for associated conductors and equipment.
What fuse size is the NH000GS69V25PV?
It uses the compact NH Size 000 format with knife-blade contacts for installation in a compatible NH fuse base or switch-fuse unit.
Can an aR fuse replace this gS fuse?
Not automatically. An aR fuse normally provides partial-range short-circuit protection, whereas this gS fuse is intended to provide full-range protection. Any substitution should be confirmed through an electrical coordination study and the equipment manufacturer's requirements.
Where is this fuse typically installed?
It is commonly fitted in drives, converters, inverters, UPS systems, industrial power supplies and other equipment containing sensitive semiconductor components.
Trusted Protection from Mersen
