Why Choose the Mersen FR14GR69V63 Protistor® Semiconductor Fuse?
The Mersen FR14GR69V63 is a high speed gR semiconductor fuse designed to provide dependable protection for sensitive power semiconductor devices. Part of the established Mersen Protistor® 14×51 gR series, it rapidly interrupts damaging overcurrents to help protect components such as IGBTs, thyristors, diodes and rectifiers used in industrial power electronic systems.
This cylindrical fuse combines an extremely high interrupting rating with effective current limitation, helping reduce thermal and mechanical stress during electrical faults. Its compact ceramic body and standard ferrule terminals allow straightforward installation in compatible 14×51 mm fuse holders and clips.
With a rated current of 63 A, a 690 V AC IEC voltage rating and a breaking capacity of 160 kA, the FR14GR69V63 is suitable for variable frequency drives, power converters, inverters, UPS equipment and other applications requiring fast and reliable semiconductor protection.
