Why Choose the Mersen FR14GR69V1 High-Speed Semiconductor Fuse?
The Mersen FR14GR69V1 is a high-performance Protistor® high-speed cylindrical semiconductor fuse designed to provide full-range protection for sensitive power semiconductor devices used in industrial power electronic equipment. As part of the trusted Mersen Protistor® 14 × 51 mm gR series, this fuse is engineered to protect IGBTs, SCRs, diodes and other semiconductor components from damaging overloads and short circuits.
Manufactured in accordance with IEC 60269-1 and IEC 60269-4, the FR14GR69V1 offers outstanding current-limiting performance and a high breaking capacity, helping minimise equipment damage and reduce downtime. Its compact cylindrical construction allows straightforward installation into compatible fuse holders used throughout industrial automation and power conversion systems.
With a 1 A current rating, 690 V AC IEC / 700 V AC UL voltage rating and 14 × 51 mm cylindrical body, the FR14GR69V1 is ideal for low-current semiconductor protection in drives, UPS systems, converters and industrial control equipment. This version is supplied without an integrated striker indicator.
