Why Choose the Mersen FR10GR69V6 High-Speed Semiconductor Fuse?
The Mersen FR10GR69V6 is a compact Protistor® high-speed cylindrical fuse intended to protect sensitive semiconductor devices in industrial power-electronic equipment. With a nominal current rating of 6 A, a voltage rating of 690 V AC and a compact 10 × 38 mm cylindrical format, it is suitable for applications where rapid fault interruption and low let-through energy are required.
Its gR utilisation category provides full-range semiconductor protection, covering both overload and short-circuit fault conditions within the limits of the selected installation. This makes the FR10GR69V6 suitable for protecting components such as diodes, thyristors, IGBTs and associated power-conversion circuitry.
The cylindrical body allows straightforward installation in a compatible 10 × 38 mm fuse holder. For correct protection, the fuse rating, holder, conductor size, operating temperature and equipment manufacturer's coordination requirements should all be verified before installation.
Key Advantages
- Fast-acting protection for sensitive semiconductor devices.
- 6 A current rating for lower-current power-electronic circuits.
- 690 V AC voltage capability.
- gR full-range protection for overloads and short circuits.
- Low let-through energy helps limit damage during electrical faults.
- Compact 10 × 38 mm cylindrical construction.
Key Features
- Mersen Protistor® high-speed fuse technology.
- Nominal current rating of 6 A.
- Nominal voltage rating of 690 V AC.
- gR semiconductor fuse classification.
- Compact cylindrical fuse-link design.
- Suitable for compatible 10 × 38 mm fuse holders.
- Rapid current limitation during fault conditions.
- Designed for professional industrial electrical installations.
Fast Protection for Power-Electronic Circuits
Semiconductor components can be damaged by fault energy before conventional general-purpose protection devices operate. The Mersen FR10GR69V6 is designed to react rapidly and restrict the current and energy passed into the protected circuit, helping reduce the risk of catastrophic damage to valuable electronic components.
Its compact construction makes it particularly useful in control panels and electronic assemblies where installation space is limited. Correct fuse coordination remains essential, and the circuit's prospective fault current, steady-state load, inrush characteristics and thermal conditions should be considered during selection.
Typical Applications
- Variable-frequency drives.
- Industrial inverters.
- Power converters and rectifiers.
- Uninterruptible power supplies.
- Servo-drive systems.
- Industrial power supplies.
- Automation and control equipment.
