Why Choose the Mersen FR10AM69V1 Cylindrical Fuse Link?
The Mersen FR10AM69V1 is a compact and dependable 10 × 38 mm aM cylindrical fuse link designed to protect motor circuits and associated switchgear against damaging short-circuit currents. Rated at 1 A and 690 V AC, it is suitable for low-current industrial control applications operating at elevated system voltages.
As an aM partial-range fuse, the FR10AM69V1 is engineered to tolerate normal motor starting currents while providing rapid interruption of severe fault currents. Its high current-limiting performance and low thermal let-through help reduce stress on contactors, cables and other components within motor control circuits.
The fuse features a durable ceramic body and silver-plated copper ferrule contacts for reliable electrical performance. Its standard cylindrical dimensions allow straightforward installation in compatible 10 × 38 mm fuse holders and mounting clips used in industrial control panels and machinery.

Reliable Protection for Industrial Motor Circuits
The Mersen FR10AM69V1 is designed to interrupt unacceptable short-circuit currents while allowing the temporary inrush currents associated with motor starting. Its aM characteristic makes it well suited to protecting motor control switchgear, contactors and related electrical equipment.
Because an aM fuse provides partial-range protection, it should be coordinated with a suitable overload relay or motor protection device. Together, these components provide effective protection against both overload conditions and severe short-circuit faults.
Typical Applications
- Industrial motor control circuits.
- Motor starters and contactors.
- Control panels and switchgear assemblies.
- Machine building and OEM equipment.
- Pumps, fans and conveyor systems.
- Industrial automation equipment.
- High-inrush inductive loads.
