Why Choose the ABB OFAA000AM6 6 A aM Motor Fuse?
The ABB OFAA000AM6, ABB order code 1SCA022660R8110, is a DIN-type HRC fuse link designed for motor-circuit protection. Rated at 6 A and 690 V AC, this exact fuse combines the aM utilisation category with the compact NH000 / size 000 format for use with compatible industrial fuse bases and switch-fuse equipment.
As an aM motor fuse, the OFAA000AM6 provides partial-range protection primarily against short-circuit currents. Its operating characteristic is designed to accommodate the temporary inrush currents associated with motor starting, while sustained overload protection is normally provided separately by an appropriately coordinated overload relay or motor-protection device.
The OFAA000AM6 has a rated power loss of approximately 0.3 W and a net weight of approximately 0.12 kg. Manufactured to IEC 60269, it provides a compact protection solution for industrial motor starters, machinery and motor-control systems operating at voltages up to 690 V AC.

Coordinated Short-Circuit Protection for Motor Circuits
Electric motors can draw considerably more than their normal running current while starting, requiring protection that can tolerate this temporary inrush without unnecessary fuse operation. The aM characteristic of the ABB OFAA000AM6 is designed for this purpose, providing short-circuit protection while accommodating the normal starting behaviour of correctly coordinated motor circuits.
Because an aM fuse is a partial-range fuse, the OFAA000AM6 is normally used alongside a suitable overload relay or other motor overload-protection device. When correctly selected and coordinated, it provides dependable fault-current protection for motor starters, industrial machinery and motor-control assemblies.
Typical Applications
- Industrial motor circuits.
- Direct-on-line motor starters.
- Motor control centres.
- Pumps, fans and compressors.
- Conveyors and material-handling equipment.
- Industrial machinery and production equipment.
- 690 V AC systems requiring NH000 aM motor fuse protection.
