Why Choose the ABB OFAA000AM16 16A aM Fuse Link?
The ABB OFAA000AM16 is a 16 A, 690 V AC DIN-type HRC fuse link designed specifically for motor circuit protection. With an aM utilisation category and compact NH size 000 construction, it provides reliable short-circuit protection for motor circuits when used as part of a correctly coordinated motor protection system.
The aM characteristic is intended for motor applications where the fuse link provides short-circuit protection while a separate overload protection device handles sustained motor overload conditions. This arrangement allows the fuse to tolerate the high transient currents associated with motor starting without unnecessarily interrupting the circuit.
This exact ABB OFAA000AM16, identified by ABB order code 1SCA022660R8370, has a rated current of 16 A, rated voltage of 690 V AC, power loss of approximately 0.7 W and a unit weight of approximately 0.12 kg.

Reliable Short-Circuit Protection for Motor Circuits
Motor circuits present different protection requirements from many general-purpose electrical loads because motors can draw substantial current during starting. An aM fuse link is designed to accommodate these starting conditions while providing high-capacity protection against short-circuit faults within the motor circuit.
The ABB OFAA000AM16 should therefore be coordinated with appropriate motor overload protection, such as a thermal or electronic overload relay. Together, the fuse and overload device can provide complementary protection against high fault currents and sustained overload conditions in industrial motor installations.
Typical Applications
- Industrial motor starter circuits.
- Three-phase motor protection systems.
- Motor control centres.
- Pumps, fans and conveyor installations.
- Industrial machinery and production equipment.
- DIN-type fuse bases and fuse-switch assemblies requiring NH size 000 aM fuse links.
