Why Choose the Mersen FR10AM69V10 Cylindrical Fuse-Link?
The Mersen FR10AM69V10 is a high-quality 10 × 38 mm aM cylindrical fuse-link designed to provide dependable short-circuit protection for motors, transformers and other industrial loads with high inrush currents. Its partial-range operating characteristic allows normal starting currents to pass while providing rapid interruption during severe electrical faults.
As part of the established Mersen FR10 aM ferrule fuse-link range, the FR10AM69V10 is manufactured for reliable performance in industrial control panels, machinery and motor starter assemblies. Its current-limiting action helps reduce the thermal and mechanical stresses placed on cables, contactors and connected equipment during a short circuit.
With a rated current of 10 A, an IEC rated voltage of 690 V AC and a compact 10 × 38 mm cylindrical format, the FR10AM69V10 is suitable for space-conscious industrial installations. As an aM fuse-link, it should be coordinated with a suitable thermal or electronic overload relay to provide complete motor circuit protection.
Key Advantages
- Purpose-designed for motor circuit short-circuit protection.
- 10 A rated current for industrial motor and machinery applications.
- 690 V AC IEC voltage rating.
- 120 kA breaking capacity at 690 V AC.
- aM characteristic accommodates normal motor starting currents.
- Compact 10 × 38 mm format simplifies panel installation.
Key Features
- Mersen FR10 aM ferrule fuse-link series.
- 10 A rated current.
- 690 V AC rated voltage.
- 10 × 38 mm cylindrical fuse format.
- aM partial-range motor protection characteristic.
- Non-indicating fuse-link design.
- High current-limiting performance.
- Suitable for loads with high starting or inrush currents.
Reliable Protection for High-Inrush Industrial Loads
The Mersen FR10AM69V10 is engineered to protect motor circuits and other inductive loads against damaging short-circuit currents. Its aM operating characteristic allows temporary motor starting currents to flow without unnecessary fuse operation while rapidly limiting dangerous fault energy.
Because the FR10AM69V10 provides partial-range protection, it does not replace an overload relay. When correctly coordinated with thermal or electronic overload protection, it helps provide comprehensive protection for motors, contactors, conductors and starter assemblies.
Typical Applications
- Industrial motor starters.
- Motor control panels.
- Transformers and inductive loads.
- Contactors and switching assemblies.
- OEM production machinery.
- Factory automation equipment.
