Reliable Protection for Power Electronic Equipment
Semiconductor devices can be damaged by fault currents within a very short period. The Mersen FR10GR69V2.5 is engineered to interrupt faults rapidly and restrict the amount of electrical energy that reaches protected components. This helps reduce thermal and mechanical stress while supporting reliable operation of power electronic equipment.
Its gR full-range characteristics provide protection against both overload and short-circuit currents. The fuse is therefore well suited to industrial systems where sensitive semiconductor components require faster and more precise protection than conventional general-purpose fuses can provide.
Typical Applications
- Variable frequency drives and motor control equipment.
- Industrial rectifiers and power supplies.
- Inverters and frequency converters.
- UPS and battery power systems.
- Semiconductor switching circuits.
- Industrial automation and control panels.
