Why Choose the Mersen FR22AR69V100 Protistor® Semiconductor Fuse?
The Mersen FR22AR69V100, also identified by item number E1027322, is a high-speed Protistor® cylindrical semiconductor fuse designed to protect sensitive power semiconductor devices against damaging short-circuit currents. As part of the Mersen Protistor® 22 × 58 mm aR series, it delivers rapid fault interruption for industrial power electronic systems operating at up to 690 V AC.
With a 100 A current rating, aR operating characteristic and exceptionally high 160 kA breaking capacity, the FR22AR69V100 is ideally suited to protecting IGBTs, thyristors, diodes and other semiconductor devices used in variable speed drives, UPS systems, power converters and industrial automation equipment.
Its compact 22 × 58 mm cylindrical design, ceramic construction and silver-plated copper ferrules provide reliable performance in demanding industrial environments while ensuring compatibility with suitable cylindrical fuse holders and fuse clips.
