Mersen F083656 Protistor high-speed cylindrical semiconductor fuse rated at 63 A and 1000 V DC, with a 100 kA breaking capacity and integrated striker indication.
£69.89
The Mersen F083656, also identified by catalogue number FD20GC100V63T, is a high-speed cylindrical fuse designed specifically for the protection of semiconductor devices and critical DC auxiliary circuits. Part of the Mersen Protistor® 20 × 127 mm gR range, it provides fast, full-range overcurrent protection for demanding industrial power systems.
This fuse features a gRC characteristic with extremely fast current-limiting performance and low let-through energy. These characteristics help reduce thermal and electrical stress on valuable semiconductor components during overload and short-circuit conditions, improving equipment protection and system reliability.
With a rated current of 63 A, an IEC voltage rating of 1000 V DC and a maximum breaking capacity of 100 kA DC, the F083656 is suitable for high-power control, measuring and monitoring circuits. Its integrated striker provides clear fuse-operation indication and can support remote monitoring when installed in compatible equipment.
High-speed fuses such as the Mersen F083656 are designed to interrupt damaging fault currents before excessive energy reaches sensitive semiconductor devices. Their extremely fast response and low I²t characteristics provide a higher level of protection than conventional industrial fuse-links in power electronic applications.
The F083656 provides full-range protection against overload and short-circuit currents while maintaining excellent cycling capability. Its 100 kA interrupting capacity makes it suitable for installations where substantial fault currents may occur, including converters, rectifiers and industrial DC systems.
