Why Choose the ABB OFAF0AM200 200A aM Motor DIN Fuse Link?
The ABB OFAF0AM200 is a robust 200 A HRC DIN fuse link designed specifically for short-circuit protection of motor circuits in demanding industrial electrical installations. Part of the ABB OFAF range, it features an aM utilisation category developed for motor applications where high starting currents must be accommodated without unnecessary fuse operation.
With a rated current of 200 A and a rated voltage of 500 V AC, the OFAF0AM200 provides dependable protection for motor feeders, starters and associated switching equipment. Its aM operating characteristic is intended for coordination with a separate overload protection device, providing effective short-circuit protection while allowing the temporary current associated with motor starting.
The NH0 / size 0 DIN format provides a standard industrial construction for installation in compatible NH fuse bases and switch-fuse equipment. With a power loss of 11.8 W at rated current, the OFAF0AM200 is suitable for motor control centres, machinery panels and other high-current industrial motor applications.

Reliable Short-Circuit Protection for Motor Circuits
aM fuse links are specifically designed for motor circuits, providing short-circuit protection while tolerating the temporary high currents associated with motor starting. This partial-range operating characteristic helps prevent unwanted fuse operation during normal motor acceleration while maintaining dependable protection against severe fault currents.
Because an aM fuse is intended primarily for short-circuit protection rather than overload protection, the OFAF0AM200 is normally coordinated with a thermal overload relay, electronic motor protection device or other suitable overload protection. This combination provides effective protection for industrial motors, starters and associated power circuits.
Typical Applications
- Industrial motor protection circuits.
- Motor starters and motor control centres.
- Pumps, fans and compressor systems.
- Conveyors and material handling equipment.
- Manufacturing and processing machinery.
- Industrial automation and machinery control panels.
