Why Choose the Mersen FR22GR69V100T Protistor® Semiconductor Fuse?
The Mersen FR22GR69V100T, item number F1018629, is a high-speed Protistor® cylindrical semiconductor fuse designed to provide full-range protection for sensitive power semiconductor devices. Part of Mersen's 22 × 58 mm gR series, it is engineered for industrial power electronic systems operating at up to 690 V AC (IEC) and 700 V AC (UL). The "T" suffix denotes the integrated striker indicator, enabling rapid visual indication and remote signalling of fuse operation.
With a 100 A current rating, gR full-range operating characteristic and an exceptionally high 160 kA AC breaking capacity, the FR22GR69V100T provides reliable protection for IGBTs, thyristors, diodes, rectifiers and other semiconductor devices used in variable speed drives, UPS systems, renewable energy converters and industrial power supplies.
Its robust ceramic body, silver-plated copper ferrules and low let-through energy minimise thermal and mechanical stress on expensive semiconductor components, while the integrated striker allows fast fault identification and compatibility with remote monitoring systems.
