Why Choose the Mersen FR10GR69V5 High-Speed Semiconductor Fuse?
The Mersen FR10GR69V5 is a compact Protistor® high-speed cylindrical fuse designed to protect sensitive power semiconductor devices in industrial power electronic equipment. Its rapid operating characteristics help limit damaging fault energy before it reaches components such as diodes, thyristors, IGBTs and rectifier assemblies.
Featuring a gR utilisation category, the FR10GR69V5 provides full-range semiconductor protection within correctly designed electrical circuits. Its current-limiting performance makes it suitable for applications where conventional general-purpose fuses may not operate quickly enough to protect valuable electronic components.
With a rated current of 5 A, a rated voltage of 690 V AC and a compact 10 × 38 mm cylindrical body, the Mersen FR10GR69V5 is suitable for compatible fuse holders installed in drives, power converters, control panels and industrial automation systems.

Reliable Protection for Power Electronic Equipment
Power semiconductor devices can be damaged by fault currents in a fraction of a second. The Mersen FR10GR69V5 is engineered to interrupt these currents rapidly while limiting the thermal and electrical energy passed into the protected circuit.
This high-speed response helps reduce stress on electronic components and can minimise equipment damage, repair costs and unplanned production downtime. Correct fuse coordination should be confirmed using the requirements of the protected semiconductor device and the associated electrical circuit.
Typical Applications
- Variable frequency drives and motor control equipment.
- Industrial inverters and power converters.
- Rectifiers and controlled power supplies.
- UPS and battery-backed power systems.
- Servo drives and automation equipment.
- Industrial control panels and OEM machinery.
