Why Choose the Mersen FR14GR69V16T High-Speed Fuse?
The Mersen FR14GR69V16T is a high-performance 16 A cylindrical semiconductor fuse designed to provide rapid and dependable protection for sensitive power electronic equipment. Part of the trusted Mersen Protistor® 14 × 51 mm gR fuse series, it delivers full-range protection against both overloads and short-circuit currents in demanding industrial applications.
Featuring a gR operating characteristic, this high-speed fuse is specifically engineered to protect semiconductor devices throughout the complete operating range. Its low let-through energy and exceptionally high interrupting capacity help minimise damage to IGBTs, thyristors, rectifiers, inverters, variable frequency drives and other critical power electronic equipment.
With a rated current of 16 A, an IEC rated voltage of 690 V AC and an integrated striker indicator, the FR14GR69V16T provides reliable protection while allowing rapid identification of an operated fuse during maintenance.
