1SCA022660R8610 ABB 32 A Size 000 aM DIN Fuse Link 690 V

Why Choose the ABB OFAA000AM32 32 A aM Fuse Link?

The ABB OFAA000AM32 is a high-performance DIN-type HRC fuse link designed specifically for motor circuit protection in industrial electrical installations. Identified by ABB order code 1SCA022660R8610, it forms part of the ABB 311002-Fuses And Fusebases product group and combines a compact NH000 / size 000 format with an aM utilisation category for dependable motor-circuit protection.

As an aM fuse link, the OFAA000AM32 is intended for short-circuit protection of motor circuits and is designed to withstand the high transient currents associated with motor starting. It is normally used together with suitable overload protection, allowing the fuse link to provide high-level short-circuit protection while the associated overload device protects the motor against sustained overload conditions.

With a rated current of 32 A and rated operational voltage of 690 V AC, the OFAA000AM32 is suitable for a wide range of industrial motor control and protection applications. Its standard NH000 / size 000 DIN fuse format allows installation in compatible NH fuse bases, fuse holders and switch-fuse equipment.

Reliable Fuse Protection for Motor Circuits

aM fuse links such as the ABB OFAA000AM32 are specifically designed for motor circuits, where normal starting currents can be substantially higher than the motor's running current. The aM operating characteristic allows these temporary starting currents while providing rapid protection against high short-circuit currents that could otherwise damage cables, switching equipment and other components.

Because an aM fuse is intended primarily for short-circuit protection, it is normally coordinated with a suitable motor overload protection device. This combination provides effective protection across the motor circuit while allowing the OFAA000AM32 to be selected as part of coordinated ABB contactor, overload relay and switch-fuse installations.

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 NH fuse bases and switch-fuse installations.
