Why Choose the Mersen M076302 High-Speed Semiconductor Fuse?
The Mersen M076302 is a high-performance Protistor® high-speed cylindrical fuse-link designed to protect sensitive semiconductor devices against damaging short-circuit currents. Identified by catalogue number FD27GB66V10T, 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 rapid fault interruption with low let-through energy, helping to minimise electrical and thermal damage to protected components. Its low I²t performance, reduced power losses and extended operating life make it suitable for modern DC equipment requiring faster protection than conventional industrial fuse-links can provide.
With a rated current of 10 A, an IEC voltage rating of 660 V DC and a compact 27 × 60 mm cylindrical format, the Mersen M076302 provides dependable protection for power converters, rectifiers, railway systems and industrial DC circuits. Its integrated striker provides a clear indication when the fuse-link has operated.
