1SCA022701R1770 ABB 80 A aM NH00 690 V HRC Motor Fuse Link

Why Choose the ABB OFAA00AM80 80 A aM HRC Fuse Link?

The ABB OFAA00AM80 is an 80 A aM HRC DIN fuse link designed for short-circuit protection of industrial motor circuits. Identified by ABB product ID 1SCA022701R1770, this NH00 / size 00 fuse link is rated for operation at up to 690 V.

Its aM utilisation category provides partial-range protection specifically intended for motor circuits. The OFAA00AM80 is designed to interrupt short-circuit and high fault currents while a separate overload relay, manual motor starter or other suitable protective device provides protection against sustained motor overload conditions.

The OFAA00AM80 combines an 80 A current rating with a compact DIN size 00 format and approximately 3.6 W power loss at rated current. Its HRC construction makes it suitable for coordinated motor protection in motor control centres, machinery and industrial power-distribution systems.

Reliable Short-Circuit Protection for Motor Circuits

An aM fuse link is specifically intended for motor applications and provides partial-range protection against short-circuit currents. The ABB OFAA00AM80 is therefore normally coordinated with an overload relay, manual motor starter or other dedicated overload-protection device to provide comprehensive protection of the motor circuit.

During a severe fault, the HRC fuse link interrupts the fault current and provides current-limiting action, helping reduce the energy passed through to downstream equipment. With an 80 A rating, 690 V voltage rating and NH00 construction, the OFAA00AM80 is well suited to industrial motor starters and power-control assemblies.

Typical Applications

• Industrial motor starter circuits.
• Motor control centres.
• Pumps, fans and compressors.
• Conveyors and material handling systems.
• Industrial machinery and process equipment.
• Motor power distribution systems.
