Why Choose the Mersen FR10GR69V10 Protistor® High-Speed Fuse?
The Mersen FR10GR69V10, manufacturer item number A1014576, is a high-speed cylindrical semiconductor fuse designed to protect sensitive power-electronic equipment against short circuits and overload currents. Part of the Mersen Protistor® range, this compact 10 × 38 mm fuse features a fast-acting, full-range gR operating characteristic.
Rated at 10 A and 690 V AC IEC, the FR10GR69V10 delivers a maximum breaking capacity of 160 kA. Its low melting and clearing energy help limit the thermal and electrodynamic stress imposed on semiconductor components during fault conditions, supporting improved equipment reliability and reduced downtime.
The ceramic body and silver-plated copper ferrules provide durable insulation, dependable conductivity and straightforward clip-mounted installation. Designed in accordance with IEC 60269-4, the fuse is suitable for inverters, uninterruptible power supplies, variable-speed drives and other equipment containing discrete semiconductor devices.

Full-Range Semiconductor Protection
Power semiconductor devices can be damaged by fault energy before a conventional industrial fuse has time to operate. The Mersen FR10GR69V10 uses a fast gR characteristic to provide full-range protection against both high short-circuit currents and lower overload currents, helping protect valuable semiconductor components throughout a broad operating range.
Its low I²t performance limits the energy allowed to pass through the circuit during fuse operation. This makes the FR10GR69V10 particularly suitable for power-conversion equipment where rapid current interruption, reliable overload protection and compact installation are essential.
Typical Applications
- Variable-speed drives.
- Industrial inverters.
- Uninterruptible power supplies.
- Power converters and rectifiers.
- Industrial motor-control equipment.
- Semiconductor power supplies.
- Renewable-energy conversion systems.
- Equipment containing discrete semiconductor devices.
