Why Choose the ABB OFAF2AM63 63A aM DIN Size 2 Motor Fuse Link?
The ABB OFAF2AM63 is a 63 A aM DIN fuse link designed specifically for short-circuit protection in industrial motor circuits. Part of the ABB OFAF range, it uses the established DIN size 2 format for integration with compatible industrial fuse bases and fuse-switch equipment.
Rated at 500 V, the OFAF2AM63 uses an aM utilisation category intended for motor-circuit protection. The aM characteristic is designed to accommodate the temporary high currents associated with motor starting while providing protection against short-circuit faults.
The combination of a 63 A current rating, 500 V voltage rating and DIN size 2 construction makes the OFAF2AM63 a practical choice for motor feeders, motor control centres, starter assemblies and industrial machinery where coordinated motor protection is required.
Key Advantages
- 63 A rated current for industrial motor circuits.
- 500 V rated voltage for low-voltage motor applications.
- aM motor-protection characteristic designed primarily for short-circuit protection.
- DIN size 2 format for compatible industrial fusegear.
- Designed to accommodate normal motor starting currents.
- Suitable for coordinated protection with a separate motor overload device.
- Replaceable fuse-link format supports straightforward industrial maintenance.

Reliable Short-Circuit Protection for Industrial Motors
aM fuse links are partial-range protective devices intended primarily for short-circuit protection of motor circuits. Their operating characteristic allows them to tolerate the temporary high currents associated with motor starting while interrupting significant fault currents when required.
Because an aM fuse is not intended to provide full-range overload protection, the ABB OFAF2AM63 is normally coordinated with a suitable overload relay, motor protection circuit breaker or equivalent protective device. This coordinated approach provides both short-circuit and overload protection while supporting reliable motor starting and operation.
Typical Applications
- Industrial motor feeder protection.
- Motor control centres and starter assemblies.
- Three-phase motor circuits.
- Pumps, fans and compressor systems.
- Conveyors and materials-handling equipment.
- Production and process machinery.
- Compatible DIN size 2 fuse bases and fuse-switch assemblies.
