Why Choose the Mersen L076301 High-Speed Semiconductor Fuse?
The Mersen L076301 is a high-performance Protistor® high-speed cylindrical fuse designed to protect sensitive semiconductor components and DC electrical circuits against damaging short-circuit currents. Identified by catalogue number FD27GB66V8T, it forms part of the Mersen Protistor® 27 × 60 mm gR (gRB) range developed for demanding railway power and auxiliary circuit applications.
This fuse-link provides rapid fault interruption with low let-through energy, helping to minimise thermal and electrical stress on protected semiconductor devices. Its low I²t characteristics, reduced watt losses and long operating life make it suitable for modern DC equipment that requires faster and more precise protection than conventional industrial fuse-links.
With a rated current of 8 A, an IEC voltage rating of 660 V DC and a compact 27 × 60 mm cylindrical format, the Mersen L076301 provides dependable protection for railway systems, power converters and industrial DC equipment. Its integrated striker allows quick identification when the fuse has operated.
