The Mersen F076825, catalogue number FR27UD69V200T, is a high-speed Protistor® cylindrical semiconductor fuse engineered to provide ultra-fast protection for sensitive power semiconductor devices operating in industrial power electronic systems. Part of the Mersen Protistor® 27 × 60 mm aR (URGD) series, it is designed for circuits operating at up to 690 V AC and complies with IEC 60269-1 and IEC 60269-4.
With a 200 A current rating, aR operating characteristic and an integrated striker indicator, the FR27UD69V200T provides dependable short-circuit protection for IGBTs, thyristors, diodes, rectifiers and other semiconductor devices used in industrial drives, power converters, UPS systems and renewable energy equipment.
Its ceramic cylindrical body, silver-plated copper ferrules and exceptionally high breaking capacity help minimise let-through energy during fault conditions, reducing damage to expensive semiconductor components while improving system reliability and reducing downtime.
The Mersen F076825 is designed to interrupt extremely high fault currents before excessive thermal energy can damage sensitive semiconductor devices. Its current-limiting performance helps improve equipment reliability while reducing maintenance costs and production downtime in demanding industrial applications.
The integrated striker indicator enables rapid fault identification and supports remote signalling when used with compatible accessories, simplifying maintenance of industrial electrical systems.
