Fast-acting aR-class cylindrical fuse designed for semiconductor protection up to 100A at 690V AC with a compact 22x58mm ceramic body and silver-plated copper terminals.
£27.68
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.
The Mersen FR22AR69V100 is engineered to interrupt high fault currents before excessive thermal energy can damage expensive semiconductor devices. Its current-limiting performance and low I²t values help maximise equipment reliability while reducing maintenance costs and production downtime.
The aR operating class provides short-circuit protection specifically for semiconductor devices. Overload protection should be provided separately, making this fuse ideal for modern industrial drives, converters and power electronic systems.
