Why Choose the ABB OFAF0AM125 125A aM Motor DIN Fuse?
The ABB OFAF0AM125 is a 125 A aM motor DIN fuse link designed for dependable short-circuit protection in industrial motor circuits. Part of ABB's OFAF fuse link range, it combines a motor-specific fuse characteristic with a standardised DIN size 0 format for integration into compatible motor-control and fusegear installations.
The OFAF0AM125 uses the aM utilisation category, which is specifically intended for motor-circuit short-circuit protection. Its partial-range characteristic is designed to accommodate the temporary high currents associated with motor starting while providing fault protection when coordinated with a suitable motor overload protection device.
With a rated current of 125 A, a rated voltage of 500 V and a DIN size 0 construction, the OFAF0AM125 is suited to industrial motor starters, motor-control centres and machinery. Its standardised DIN design enables installation in compatible fuse bases, fuse switches and other motor-control equipment.

Reliable Short-Circuit Protection for Motor Circuits
aM fuse links such as the ABB OFAF0AM125 are designed specifically for short-circuit protection in motor circuits. Their operating characteristic accommodates the elevated current associated with motor starting while enabling the fuse to interrupt damaging fault currents when a short circuit occurs.
Because the aM characteristic provides partial-range protection, the OFAF0AM125 should be coordinated with suitable overload protection for complete motor protection. This arrangement makes it suitable for motor starters, motor-control centres and industrial machinery where dedicated short-circuit and overload protection functions are combined within a coordinated protection system.
Typical Applications
- Industrial electric motor circuits.
- Motor starters and motor-control centres.
- Pumps, fans and conveyor systems.
- Industrial machinery and automation equipment.
- Electrical control panels and machine cabinets.
- Compatible DIN fuse bases and fuse switching equipment.
