1SCA022652R0610 ABB 10 A aM NH000 DIN Motor Fuse Link 500 V

Why Choose the ABB OFAF000AM10 10 A aM Motor DIN Fuse Link?

The ABB OFAF000AM10 is a compact HRC DIN fuse link designed specifically for short-circuit protection of industrial motor circuits. Identified by ABB order code 1SCA022652R0610, it forms part of the ABB 311002-Fuses And Fusebases product group and combines a 10 A rated current with the compact NH000 / DIN size 000 fuse format.

The OFAF000AM10 uses an aM utilisation category intended for motor circuit protection. Its operating characteristic is designed to accommodate the temporary high currents associated with motor starting while providing effective protection against damaging short-circuit currents. As an aM fuse provides partial-range protection, it is normally coordinated with a suitable overload relay or other motor overload protection device.

Rated for operation at up to 500 V AC, the OFAF000AM10 provides a compact solution for motor starters, control panels and machinery. Its NH000 / DIN size 000 construction enables installation in compatible DIN fuse bases and switch-fuse equipment, while its HRC design provides dependable current-limiting performance during electrical faults.

Reliable Short-Circuit Protection for Industrial Motors

aM fuse links such as the ABB OFAF000AM10 are specifically designed for motor circuits where starting currents can be considerably higher than normal running current. The aM characteristic accommodates these temporary starting currents while providing effective interruption of severe short-circuit currents that could otherwise damage cables, contactors and associated motor-control equipment.

Because the OFAF000AM10 is an aM partial-range fuse, it is normally coordinated with an appropriately selected overload relay or other overload protection device. This combination allows the fuse to provide short-circuit protection while the associated protective device responds to sustained motor overload conditions.

Typical Applications

• Industrial motor circuit short-circuit protection.
• Motor control centres and electrical control panels.
• Direct-on-line motor starter assemblies.
• Small pumps, fans and conveyor systems.
• Industrial machinery and automation equipment.
• Coordinated contactor and overload relay assemblies.
• Compatible NH000 / DIN size 000 fuse bases and switch-fuse equipment.
