Why Choose the ABB OFAF000AM25 25A aM Motor DIN Fuse Link?
The ABB OFAF000AM25 is a compact and dependable 25 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 uses an aM utilisation category that is particularly suited to motor applications where temporary starting currents must be accommodated without unnecessary fuse operation.
With a rated current of 25 A and a rated voltage of 500 V AC, the OFAF000AM25 provides reliable protection for motor feeders, starters and associated control equipment. The aM characteristic provides short-circuit protection and is normally coordinated with a separate overload protection device to provide comprehensive motor protection.
The NH000 / size 000 DIN format provides a compact installation footprint for compatible fuse bases and switch-fuse equipment. The OFAF000AM25 also features dual indication, helping maintenance personnel identify fuse operation quickly in industrial control and distribution systems.

Reliable Short-Circuit Protection for Motor Circuits
aM fuse links are designed specifically for motor circuits, providing short-circuit protection while allowing the temporary high currents associated with motor starting. This characteristic helps prevent unwanted fuse operation during normal motor acceleration while maintaining dependable protection against severe fault currents.
Because the aM characteristic is intended primarily for short-circuit protection, the OFAF000AM25 is normally coordinated with a thermal overload relay, electronic motor protection device or other suitable overload protection. Its compact NH000 construction makes it particularly useful in motor starters, machinery panels and space-conscious industrial control systems.
Typical Applications
- Industrial motor protection circuits.
- Motor starters and motor control centres.
- Pumps, fans and compressor equipment.
- Conveyors and material handling systems.
- Manufacturing and processing machinery.
- Industrial automation and machinery control panels.
