Why Choose the ABB OFAA000AM40 40A aM Motor Fuse?
The ABB OFAA000AM40 is a 40 A DIN-type HRC fuse link designed for motor circuit protection in industrial electrical systems. With an aM utilisation category, NH size 000 construction and a rated voltage of 690 V, it provides dependable short-circuit protection for motor circuits when correctly coordinated with separate overload protection.
The aM operating characteristic is specifically suited to motor applications because it permits the temporary high currents associated with motor starting while protecting the circuit against high fault currents. As a partial-range motor fuse, the OFAA000AM40 is intended to work alongside an overload relay or another suitable overload protective device.
This exact ABB OFAA000AM40, identified by ABB order code 1SCA022660R8880, has a rated current of 40 A, an NH000 fuse size and a power loss of approximately 1.8 W. Its compact DIN-type HRC construction makes it suitable for compatible fuse bases and fuse-switch equipment used throughout industrial motor-control installations.
Key Advantages
- 40 A aM motor-protection characteristic for industrial motor circuits.
- Rated for applications up to 690 V.
- Compact NH size 000 DIN-type construction.

Dependable Short-Circuit Protection for Motor Circuits
Industrial motors can draw substantially more than their normal running current while starting. The aM characteristic of the ABB OFAA000AM40 is designed around this requirement, allowing appropriate motor starting currents while providing partial-range protection against potentially damaging short-circuit currents.
Because an aM fuse is intended primarily for short-circuit protection, the OFAA000AM40 should be coordinated with suitable motor overload protection. Used together, the fuse and overload protective device provide complementary protection against high fault currents and sustained overload conditions.
Typical Applications
- Industrial motor starter circuits.
- Three-phase motor protection systems.
- Motor control centres.
- Pumps, fans and conveyor systems.
- Industrial machinery and production equipment.
- Compatible NH000 fuse bases and fuse-switch assemblies.
