Why Choose the ABB OFAA1AM100 100 A aM Motor Fuse?
The ABB OFAA1AM100 is a 100 A aM HRC DIN fuse link designed specifically for short-circuit protection of industrial motor circuits. Identified by ABB product ID 1SCA022701R2310, this DIN size 1 fuse link is rated for operation at up to 690 V AC.
Its aM utilisation category provides partial-range protection for motor circuits, interrupting high fault and short-circuit currents while a separate overload relay, manual motor starter or other suitable device protects the motor against sustained overload conditions. This makes the OFAA1AM100 suitable for coordinated motor starter assemblies.
The OFAA1AM100 combines a 100 A current rating with ABB's industrial HRC fuse-link construction and dual indication. Its DIN size 1 format is suitable for compatible fuse bases and switch-fuse equipment used in motor control centres, machinery and industrial power-distribution installations.

Current-Limiting Protection for Motor Circuits
An aM fuse link is intended specifically for motor applications and provides partial-range protection against short-circuit currents. The ABB OFAA1AM100 is therefore normally coordinated with an overload relay or another dedicated motor overload-protection device rather than being used alone for complete motor overcurrent protection.
During a severe electrical fault, the HRC fuse link interrupts the current and provides current-limiting action, helping reduce the energy passed through to contactors, conductors and other downstream components. Its 100 A rating and 690 V AC capability make the OFAA1AM100 suitable for demanding industrial motor-control systems.
Typical Applications
- Industrial motor starter circuits.
- Motor control centres.
- Pumps, fans and compressors.
- Conveyors and material handling systems.
- Industrial machinery and process equipment.
- Motor power distribution systems.
