Why Choose the Mersen FR10AM50V12 Cylindrical Fuse Link?
The Mersen FR10AM50V12 is a compact and dependable 10 × 38 mm cylindrical aM fuse link designed to protect industrial motor circuits and associated switchgear against damaging short-circuit currents. With a rated current of 12 A and an IEC voltage rating of 500 V AC, it is suitable for motor starters, machinery and industrial control equipment.
As an aM partial-range fuse, the FR10AM50V12 is designed to tolerate the temporary inrush currents produced during normal motor starting while rapidly interrupting serious short-circuit faults. It should be coordinated with a suitable overload relay or motor protection device to provide complete protection against overload and short-circuit conditions.
The fuse link features a durable ceramic body and silver-plated copper ferrule contacts for reliable conductivity, strong thermal performance and long-term operation. Its compact clip-mounted format allows straightforward installation within compatible 10 × 38 mm cylindrical fuse holders.

Reliable Short-Circuit Protection for Motor Circuits
Electric motors can draw substantially more than their normal operating current during start-up. The aM characteristic allows the Mersen FR10AM50V12 to withstand these temporary starting currents while providing rapid interruption when a high short-circuit current occurs.
Because the FR10AM50V12 is a partial-range fuse, it should be used alongside a correctly selected overload relay, motor protection circuit breaker or equivalent device. This coordinated arrangement helps protect motors, cables, contactors and control equipment against both sustained overloads and short-circuit faults.
Typical Applications
- Industrial motor starters.
- Motor control centres and control panels.
- Contactors and overload relay assemblies.
- Pumps, fans and conveyor systems.
- Industrial machinery and automation equipment.
- OEM electrical and motor control systems.
