Why Choose the Mersen FR22AR69V32T Protistor® High-Speed Fuse?

The Mersen FR22AR69V32T is a premium Protistor® high-speed cylindrical semiconductor fuse designed to provide rapid short-circuit protection for sensitive power semiconductor devices. Featuring an aR operating characteristic, it is specifically engineered to protect IGBTs, thyristors, SCRs, diodes and rectifiers used in industrial power electronic equipment. The integrated striker indicator enables quick identification of an operated fuse and can be used with compatible monitoring systems for improved maintenance efficiency.

Manufactured in accordance with IEC 60269-4, the FR22AR69V32T combines a compact 22 × 58 mm cylindrical design with an exceptionally high interrupting capacity. Its low I²t characteristics and current-limiting design minimise fault energy, helping to protect expensive semiconductor components and reduce equipment downtime.

Rated at 32 A with a 690 V AC IEC voltage rating, this fuse is ideally suited for protecting variable frequency drives, UPS systems, industrial inverters, power converters and other semiconductor-based equipment operating in demanding industrial environments.
