Why Choose the Mersen NH3UD69V900PV Semiconductor Fuse?
The Mersen NH3UD69V900PV is an industrial NH-format fuse intended for the protection of high-power electrical and power electronic equipment. The manufacturer reference indicates an NH Size 3 construction, a nominal 900 A current rating and a 690 V AC voltage class.
Its high-current square-body format is suited to demanding installations such as industrial drives, power conversion equipment, rectifier systems and heavy-duty control panels. NH blade contacts allow installation in a compatible NH Size 3 fuse base, fuse-switch disconnector or equipment-specific mounting assembly.
Public manufacturer documentation for this exact reference could not be confirmed. The utilisation category, breaking capacity, I²t values, power dissipation, dimensions and indicator configuration should therefore be checked against the fuse label, original equipment documentation or a current Mersen technical datasheet before ordering or installation.
Key Advantages
- High-current fuse for demanding industrial equipment.
- 900 A nominal current rating indicated by the product reference.
- 690 V AC voltage class indicated by the product reference.
- Standard industrial NH Size 3 construction.
- Suitable for compatible fuse bases and fuse-switch disconnectors.
- Designed for high-power electrical protection applications.
Key Features
- Manufacturer: Mersen.
- Manufacturer reference: NH3UD69V900PV.
- Nominal current: 900 A.
- Voltage class: 690 V AC.
- Fuse size: NH Size 3.
- Square-body industrial construction.

High-Current Industrial Circuit Protection
High-current fuse selection requires more than matching the physical NH size and ampere rating. The voltage rating, utilisation category, breaking capacity, time-current performance, I²t characteristics and mounting arrangement must also be suitable for the protected equipment and prospective fault current.
When replacing an existing NH3UD69V900PV fuse, the complete manufacturer reference should be checked against the original component. A physically compatible NH Size 3 fuse with a different operating characteristic may not provide equivalent protection.
Typical Applications
- High-power industrial drives.
- Power converters and inverter systems.
- Industrial rectifier assemblies.
- Heavy-duty motor-control equipment.
- Power distribution panels.
- Uninterruptible power supply systems.
- Renewable-energy conversion equipment.
- OEM industrial machinery.

Frequently Asked Questions
What is the Mersen NH3UD69V900PV used for?
The NH3UD69V900PV is intended for high-current industrial electrical protection. Its precise suitability depends on the required utilisation category, fault-current rating and time-current performance.
What is the current rating of the NH3UD69V900PV?
The product reference indicates a nominal current rating of 900 A. This should be confirmed from the fuse label or current manufacturer documentation.
What is its voltage rating?
The product reference indicates a 690 V AC voltage class. The applicable operating voltage and installation standard should be verified before use.
What physical size is the NH3UD69V900PV?
The reference indicates an NH Size 3 format for use with compatible NH fuse bases, switches and mounting equipment.
Is the NH3UD69V900PV a semiconductor fuse?
The exact utilisation category for this reference could not be confirmed from current public manufacturer documentation. Check for an aR, gR, gS or other classification on the fuse label or official datasheet before describing it as a semiconductor-protection fuse.
Can another 900 A NH Size 3 fuse replace it?
Not automatically. The complete part number, voltage rating, utilisation category, breaking capacity, I²t performance, dimensions and contact arrangement must match the equipment specification.
