Why Choose the ABB OFAF000AM80 80A aM Motor DIN Fuse Link?
The ABB OFAF000AM80 is a compact and reliable 80 A HRC DIN fuse link designed specifically for short-circuit protection of motor circuits in industrial electrical installations. Part of the ABB OFAF range, it features an aM utilisation category suited to motor applications where temporary starting currents need to be accommodated without unnecessary fuse operation.
With a rated current of 80 A and a rated voltage of 500 V AC, the OFAF000AM80 is suitable for protecting motor feeders and associated switching equipment against short-circuit faults. Its aM operating characteristic is intended to be coordinated with a separate overload protection device for comprehensive motor protection.
The NH000 / size 000 DIN format provides a space-efficient solution for installation in compatible fuse bases and switch-fuse equipment. Its HRC construction provides dependable fault interruption, making the OFAF000AM80 suitable for motor control centres, machinery panels and industrial automation systems.

Reliable Short-Circuit Protection for Motor Circuits
aM fuse links are specifically designed for motor circuits, providing short-circuit protection while tolerating the temporary high currents associated with motor starting. This characteristic helps prevent unwanted fuse operation during normal acceleration while maintaining protection against severe electrical faults.
Because an aM fuse provides partial-range protection intended primarily for short-circuit faults, the OFAF000AM80 is normally coordinated with a thermal overload relay, electronic motor protection device or other suitable overload protection. This makes it a practical solution for industrial motor starters and machinery protection systems.
Typical Applications
- Industrial motor protection circuits.
- Motor starters and motor control centres.
- Pumps, fans and compressor systems.
- Conveyors and material handling equipment.
- Manufacturing and processing machinery.
- Industrial automation and machinery control panels.
