Why Choose the Mersen FR10GR69V2 High-Speed Semiconductor Fuse?
The Mersen FR10GR69V2 is a compact Protistor® high-speed cylindrical semiconductor fuse designed to protect sensitive power electronic components against damaging overcurrents and short circuits. Its rapid operating response limits the amount of fault energy reaching semiconductor devices, helping to reduce equipment damage and unplanned downtime.
As part of the Mersen Protistor® 10 × 38 mm gR fuse range, the FR10GR69V2 provides full-range semiconductor protection within a space-saving cylindrical format. It is suitable for power conversion, industrial automation and motor control equipment where conventional general-purpose fuses may not operate quickly enough to protect sensitive electronic components.
With a rated current of 2 A and a rated voltage of 690 V AC, the FR10GR69V2 is suitable for protecting low-current semiconductor circuits in drives, inverters, rectifiers, UPS equipment and industrial power supplies. Its standard 10 × 38 mm dimensions allow installation in a compatible cylindrical fuse holder.

Fast Protection for Sensitive Power Electronics
Semiconductor devices such as diodes, thyristors, rectifiers and transistors can be damaged by fault currents within a very short period. High-speed fuses respond more rapidly than conventional industrial fuses and restrict the peak current and thermal energy passed into the protected circuit.
The gR operating characteristic provides protection across both overload and short-circuit conditions. This makes the Mersen FR10GR69V2 suitable for circuits requiring comprehensive semiconductor protection, subject to correct coordination with the protected equipment and the manufacturer's design requirements.
Typical Applications
- Variable speed drives and motor controllers.
- Industrial inverters and rectifiers.
- Uninterruptible power supplies.
- Power converters and industrial power supplies.
- Semiconductor modules and electronic assemblies.
- Automation and process control equipment.
