Why Choose the ABB OFAF2AM160 DIN Fuse Link?
The ABB OFAF2AM160 is a high-rupturing-capacity DIN-type aM fuse link designed for reliable short-circuit protection of motor circuits and industrial electrical equipment. Part of ABB’s OFAF fuse range, this fuse link combines a 160 A rated current, 500 V AC rated voltage and NH2 / IEC size 2 format for use in compatible fuse bases and switch-fuse equipment.
The aM utilisation category is specifically intended for motor-circuit protection, providing short-circuit protection while allowing the motor’s normal starting current to pass without unnecessary operation. Overload protection is therefore normally provided by a separate motor protection device or overload relay within the installation.
With its standard DIN/NH blade-contact construction, the OFAF2AM160 provides straightforward integration into industrial power distribution and motor control systems. ABB identifies this exact fuse as order code 1SCA022697R8890, with a power loss of approximately 9.3 W at rated current.

Reliable Short-Circuit Protection for Motor Circuits
The ABB OFAF2AM160 uses an aM fuse characteristic intended primarily for short-circuit protection in motor circuits. This characteristic is suited to applications where high motor starting currents must be tolerated while potentially damaging short-circuit currents are interrupted rapidly by the fuse link.
Because an aM fuse provides partial-range protection, it is typically coordinated with an appropriate overload protection device. This combination enables dependable protection of motors, contactors, cables and associated control equipment in industrial installations.
Typical Applications
- Industrial motor circuits.
- Motor control centres and control panels.
- Switch-fuse combinations and fuse bases.
- Pumps, fans and compressor motor circuits.
- Conveyors and material handling machinery.
- Industrial machinery and automation equipment.
