Why Choose the ABB OFAF0AM160 160A 500V aM DIN Fuse?
The ABB OFAF0AM160 is a high rupturing capacity 160 A aM motor DIN fuse link designed for dependable short-circuit protection in industrial motor circuits. Part of ABB's OFAF range, it combines a motor-specific fuse characteristic with a standardised DIN size 0 / NH0 format for integration into compatible motor-control and fusegear installations.
The OFAF0AM160 uses the aM utilisation category, specifically intended for motor-circuit short-circuit protection. Its partial-range operating characteristic is designed to accommodate 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 160 A, a rated voltage of 500 V and a DIN size 0 / NH0 construction, the OFAF0AM160 is suitable for substantial industrial motor loads. The fuse has a power loss of approximately 10.5 W at rated current and is designed for use in compatible DIN fuse bases and switching equipment.

Reliable Short-Circuit Protection for Motor Circuits
aM fuse links such as the ABB OFAF0AM160 are designed specifically for short-circuit protection in motor circuits. Their operating characteristic accommodates the elevated current associated with motor starting while allowing the fuse to interrupt damaging fault currents when a short circuit occurs.
Because the aM characteristic provides partial-range protection, the OFAF0AM160 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 cabinets.
- Compatible DIN fuse bases and fuse switching equipment.
