OFAA1AM160 ABB 160 A Size 1 aM DIN Fuse Link 690 V

Why Choose the ABB OFAA1AM160 160 A Size 1 aM DIN Fuse Link?

The ABB OFAA1AM160 is a high-performance DIN-type HRC fuse link designed specifically for short-circuit protection of motor circuits in industrial electrical installations. It forms part of the ABB 311002-Fuses And Fusebases product group and combines a 160 A current rating with the standard DIN size 1 format.

The OFAA1AM160 uses an aM utilisation category, making it suitable for motor circuits where high transient currents occur during starting. Its operating characteristic allows normal motor starting currents while providing effective protection against damaging short-circuit currents. For complete motor protection, an aM fuse is normally coordinated with a suitable overload relay or other overload protection device.

Rated for use at up to 690 V AC, the OFAA1AM160 is designed for demanding industrial motor-control applications. Its DIN size 1 construction enables installation in compatible fuse bases and switch-fuse equipment, while its HRC design provides dependable current-limiting performance during severe fault conditions.

Reliable Short-Circuit Protection for Industrial Motors

aM fuse links such as the ABB OFAA1AM160 are specifically designed for motor circuits, where starting currents can be considerably higher than normal running current. The aM operating characteristic accommodates these temporary starting currents while providing rapid protection against severe short-circuit faults that could damage cables, contactors and other motor-control equipment.

Because an aM fuse provides partial-range protection focused on short-circuit conditions, the OFAA1AM160 is normally coordinated with a suitable overload protection device. This combination provides effective motor circuit protection while supporting reliable starting and operation in demanding industrial applications.

Typical Applications

• Industrial motor circuit short-circuit protection.
• Motor control centres and electrical control panels.
• Direct-on-line and other motor starter assemblies.
• Pumps, fans and compressor systems.
• Conveyors and material handling equipment.
• Manufacturing and processing machinery.
• Compatible DIN size 1 fuse bases and switch-fuse equipment.
