Why Choose the ABB OFAF2AM100 100A aM DIN Size 2 Motor Fuse Link?
The ABB OFAF2AM100 is a 100 A aM HRC DIN fuse link designed specifically for short-circuit protection in industrial motor circuits. Part of the ABB OFAF range, it uses the established DIN size 2 / NH2 format for integration with compatible industrial fuse bases and fuse-switch equipment.
Rated at 500 V AC, the OFAF2AM100 uses an aM utilisation category optimised for motor-circuit protection. The aM characteristic is intended to withstand normal motor starting currents while providing high fault-current protection, with separate overload protection normally provided by a coordinated motor protection device.
With a rated current of 100 A, a power loss of 5.5 W and an ABB-listed weight of 0.32 kg, the OFAF2AM100 provides a robust protection solution for motor feeders, motor control centres and industrial machinery.

Reliable Short-Circuit Protection for Industrial Motors
aM fuse links are partial-range devices intended primarily for short-circuit protection of motor circuits. Their operating characteristic allows the fuse to tolerate the temporary high currents associated with motor starting while providing rapid interruption when a significant fault current occurs.
Because an aM fuse does not provide full-range overload protection, the ABB OFAF2AM100 is normally coordinated with a suitable overload relay, motor protection circuit breaker or equivalent protective device. This arrangement provides effective protection while supporting reliable starting and operation of industrial motors.
Typical Applications
- Industrial motor feeder protection.
- Motor control centres and starter assemblies.
- Three-phase motor circuits.
- Pumps, fans and compressor systems.
- Conveyors and materials-handling machinery.
- Production and process machinery.
- Compatible DIN size 2 / NH2 fuse bases and fuse-switch assemblies.
