Why Choose the ABB OFAA000AM2 2A aM Fuse Link?
The ABB OFAA000AM2 is a compact 2 A DIN-type HRC fuse link designed specifically for motor circuit protection. With an aM utilisation category and NH size 000 construction, it provides short-circuit protection for motor circuits when correctly coordinated with a separate overload protection device.
The aM operating characteristic is particularly suited to motor applications because it allows the fuse link to accommodate normal motor starting currents while protecting the circuit against high fault currents. Sustained overload protection is provided separately by an appropriate motor overload relay or equivalent protective device.
This exact ABB OFAA000AM2 has a rated current of 2 A, a rated voltage of 690 V AC and an ABB order code of 1SCA022660R7640. Its compact NH000 format makes it suitable for compatible ABB fuse bases, switch-fuses and coordinated motor-protection assemblies.

Reliable Short-Circuit Protection for Motor Circuits
Motor circuits can draw considerably more than their normal operating current during starting. An aM fuse link is specifically intended for motor circuits and provides short-circuit protection while accommodating the temporary current increase associated with normal motor starting.
Because an aM fuse provides partial-range protection, the ABB OFAA000AM2 should be coordinated with an appropriate motor overload protection device. This combination enables the fuse to address high fault currents while the overload device protects the motor against sustained overload conditions.
Typical Applications
- Low-current industrial motor starter circuits.
- Three-phase motor protection systems.
- Motor control centres.
- Pumps, fans and small motor-driven equipment.
- Industrial machinery and automation systems.
- Compatible NH000 fuse bases and switch-fuse assemblies.
