Why Choose the Mersen FR22AM69V12 Cylindrical Fuse Link?
The Mersen FR22AM69V12 is a high-performance aM cylindrical fuse link designed to provide dependable short-circuit protection for industrial motors and other electrical loads with high starting currents. Part of the established Mersen 22 × 58 mm IEC ferrule fuse range, it is suitable for motor starters, control panels, switchgear and industrial machinery.
Its aM operating characteristic allows temporary motor starting currents to pass without unnecessary fuse operation while rapidly interrupting dangerous short-circuit currents. As a partial-range fuse link, it should be coordinated with a correctly selected overload relay, electronic motor protection device or motor protection circuit breaker.
With a rated current of 12 A, a rated voltage of 690 V AC and a compact 22 × 58 mm IEC format, the FR22AM69V12 provides effective current limitation and reliable protection for demanding motor control applications. This standard version is supplied without a striker.
Key Advantages
- Purpose-designed aM characteristic for motor circuit protection.
- 12 A current rating for industrial motors and inductive loads.
- 690 V AC rated voltage for demanding low-voltage installations.
- Allows normal motor starting currents while interrupting short-circuit faults.
- Current-limiting performance helps reduce stress on downstream equipment.
- Compact 22 × 58 mm IEC cylindrical format.
Key Features
- Mersen 22 × 58 mm aM cylindrical fuse-link series.
- 12 A rated current.
- 690 V AC rated voltage.
- Partial-range protection designed for motor circuits.
- Ceramic body for dependable thermal and mechanical performance.
- Silver-plated contacts for reliable electrical conductivity.
- Suitable for use with separate motor overload protection.
- Standard version without a striker.
Reliable Short-Circuit Protection for Motor Circuits
The Mersen FR22AM69V12 is engineered to interrupt high fault currents while tolerating the temporary inrush currents associated with motor starting. Its current-limiting action helps reduce the thermal and mechanical energy transferred to cables, contactors, switchgear and connected machinery during a short circuit.
Because the FR22AM69V12 is an aM partial-range fuse, it does not provide complete overload protection by itself. It should therefore be used alongside an appropriately rated overload relay or another suitable motor protection device to provide coordinated protection against overload and short-circuit conditions.
Typical Applications
- Industrial motor starters.
- Motor control centres.
- Machinery control panels.
- Pumps, fans and conveyor systems.
- Low-voltage switchgear assemblies.
- OEM automation and manufacturing equipment.

Frequently Asked Questions
What is the Mersen FR22AM69V12 used for?
It is used to provide short-circuit protection for industrial motors, motor starters and other electrical loads that experience high starting currents.
What are the electrical ratings of this fuse?
The FR22AM69V12 has a rated current of 12 A and a rated voltage of 690 V AC.
What does the aM fuse characteristic mean?
An aM fuse provides partial-range protection designed for motor circuits. It protects against short circuits but requires a separate device to provide overload protection.
Does the FR22AM69V12 include a striker?
No. The FR22AM69V12 is the standard version supplied without a striker. The FR22AM69V12P version should be selected where auxiliary fuse-operation signalling is required.
What size fuse holder is required?
This fuse requires a compatible IEC cylindrical fuse holder designed for 22 × 58 mm fuse links and rated for the applicable circuit voltage and current.
