Why Choose the ABB OFAF2AM315 315A 500V aM Motor DIN Fuse?
The ABB OFAF2AM315 is a high rupturing capacity 315 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 2 / NH2 format for integration into compatible motor-control and fusegear installations.
The OFAF2AM315 uses the aM utilisation category, specifically intended for motor-circuit short-circuit protection. Its partial-range operating characteristic is designed to accommodate the elevated currents associated with motor starting while providing effective fault protection when coordinated with a suitable motor overload protection device.
With a rated current of 315 A, a rated voltage of 500 V AC and a DIN size 2 / NH2 construction, the OFAF2AM315 is suitable for demanding industrial motor applications. ABB specifies a power loss of 23.1 W and a product weight of approximately 0.40 kg for this fuse link.

Reliable Short-Circuit Protection for Motor Circuits
aM fuse links such as the ABB OFAF2AM315 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 OFAF2AM315 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 production equipment.
- Electrical control panels and machine installations.
- Compatible DIN fuse bases and fuse switching equipment.
