Why Choose the ABB OFAF000AM63 63A aM Motor DIN Fuse?
The ABB OFAF000AM63 is a dependable 63 A aM motor DIN fuse link designed for short-circuit protection of motor circuits and associated industrial electrical equipment. As part of the ABB OFAF DIN-type fuse link range, it combines a motor-specific operating characteristic with high rupturing capacity construction for reliable protection in demanding electrical installations.
The OFAF000AM63 uses the aM utilisation category, specifically intended for motor-circuit protection. This partial-range fuse characteristic accommodates the temporary high currents associated with motor starting while providing effective short-circuit protection when coordinated with a suitable overload protection device.
With a rated current of 63 A, a rated voltage of 500 V AC and an NH000 / DIN size 000 format, the OFAF000AM63 provides substantial motor-circuit protection in a compact fuse size. Its DIN blade-contact construction enables integration with compatible fuse bases, fuse switches and industrial motor-control equipment.
Key Advantages
- Reliable 63 A motor-circuit short-circuit protection.
- 500 V AC rated voltage for industrial motor-control applications.
- aM utilisation category specifically designed for motor circuits.
- NH000 / DIN size 000 construction combines compact dimensions with a 63 A rating.
- Designed to accommodate normal motor starting currents when correctly coordinated.

Reliable Short-Circuit Protection for Motor Circuits
aM fuse links such as the ABB OFAF000AM63 are designed specifically for short-circuit protection in motor circuits. Their operating characteristic accommodates the elevated current associated with motor starting while enabling effective interruption of high fault currents, helping protect motors, conductors and associated switching equipment from short-circuit damage.
Because the aM characteristic provides partial-range protection, the OFAF000AM63 is intended to be coordinated with suitable overload protection for complete motor protection. This combination makes it suitable for motor starters, motor-control centres and industrial machinery where reliable protection and compact DIN fusegear integration are required.
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.
