Why Choose the Mersen FR10GR69V3 Semiconductor Fuse?
The Mersen FR10GR69V3 is a compact, ultra-fast semiconductor protection fuse designed to safeguard sensitive power electronic equipment against overload and short-circuit currents. Its fast operating characteristics help protect semiconductor devices by limiting the peak current and electrical energy permitted to pass during a fault.
Featuring a gR utilisation category, the FR10GR69V3 provides full-range protection for semiconductor circuits. This makes it suitable for installations containing diodes, thyristors, rectifiers, inverters and other electronic components that can be damaged rapidly by excessive current.
With a rated current of 3 A and a rated voltage of 690 V AC, this fuse is well suited to low-current industrial power conversion and control applications. Its compact 10 × 38 mm cylindrical format allows straightforward installation in a compatible fuse holder.
