Why Choose the Mersen P098591 High-Speed Semiconductor Fuse?
The Mersen P098591 is a high-performance Protistor® high-speed cylindrical fuse-link designed to protect sensitive semiconductor components against damaging short-circuit currents. Identified by manufacturer reference FD27GB66V2T, it forms part of Mersen’s 27 × 60 mm gR (gRB) range developed for demanding DC power and railway auxiliary applications.
This fuse-link provides extremely fast, current-limiting fault interruption with low let-through energy, helping to minimise electrical and thermal damage to protected semiconductor devices. Its low I²t characteristics, reduced power losses and extended service life make it suitable for modern DC equipment requiring faster protection than conventional industrial fuse-links can provide.
With a rated current of 2 A, an IEC voltage rating of 660 V DC and a compact 27 × 60 mm cylindrical format, the Mersen P098591 provides dependable protection for railway systems, power converters, rectifiers and industrial DC circuits. Its integrated striker provides clear fuse-operation indication for easier maintenance and fault identification.
