Why Choose the ABB OFAF1AM200 200A aM Motor DIN Fuse?
The ABB OFAF1AM200 is a high rupturing capacity 200 A aM motor DIN fuse link designed for dependable short-circuit protection in industrial motor circuits. Part of ABB's OFAF FuseLine range, it combines a motor-specific fuse characteristic with a standardised DIN size 1 / NH1 format for integration into compatible motor-control and fusegear installations.
The OFAF1AM200 uses the aM utilisation category, specifically intended for motor-circuit short-circuit protection. Its partial-range characteristic accommodates the temporary high currents associated with motor starting while providing effective fault protection when coordinated with a suitable motor overload protection device.
With a rated current of 200 A, a rated voltage of 500 V AC and a DIN size 1 / NH1 construction, the OFAF1AM200 is suited to demanding industrial motor applications. It offers a rated breaking capacity of 120 kA and a power loss of approximately 14.2 W at rated current.

Reliable Short-Circuit Protection for Motor Circuits
aM fuse links such as the ABB OFAF1AM200 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 motor circuits and associated electrical equipment against short-circuit damage.
Because the aM characteristic provides partial-range protection, the OFAF1AM200 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 operate together as a coordinated 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 installations.
- Compatible DIN fuse bases and fuse switching equipment.
