Why Choose the ABB OFAF00AM100 100A aM Motor DIN Fuse Link?
The ABB OFAF00AM100 is a robust 100 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 developed for motor applications where high starting currents need to be accommodated without unnecessary fuse operation.
With a rated current of 100 A and a rated voltage of 500 V AC, the OFAF00AM100 provides dependable protection for motor feeders, starters and associated switching equipment. Its aM operating characteristic is intended for coordination with a separate overload protection device, allowing effective protection against severe short-circuit faults while supporting normal motor starting conditions.
The NH00 / size 00 DIN format provides a standard industrial construction for installation in compatible fuse bases and switch-fuse equipment. With a rated-current power loss of 5.2 W, the OFAF00AM100 is well suited to motor control centres, machinery panels and other demanding industrial motor applications.

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 dependable protection against severe electrical faults.
Because an aM fuse is intended primarily for short-circuit protection rather than full-range overload protection, the OFAF00AM100 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, motor control centres 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.
