1SCA022701R1000 ABB 315 A gG DIN Size 3 HRC Fuse Link 690 V

Why Choose the ABB OFAA3GG315 315 A DIN Size 3 Fuse Link?

The ABB OFAA3GG315 is a high-performance HRC DIN fuse link designed for reliable overload and short-circuit protection in industrial low-voltage electrical systems. Identified by ABB order code 1SCA022701R1000, it forms part of the ABB 311002-Fuses And Fusebases product group and combines a 315 A rated current with the standard NH3 / DIN size 3 format.

The OFAA3GG315 uses a gG full-range utilisation category, making it suitable for general-purpose protection of cables, conductors, feeders and electrical equipment against both overload and short-circuit currents. Its HRC construction provides current-limiting performance during fault conditions, helping reduce the thermal and electromechanical stresses imposed on protected equipment.

Rated at 690 V AC, the OFAA3GG315 is designed for demanding industrial power distribution applications. Its NH3 / DIN size 3 construction provides a standardised format for integration with compatible fuse bases, fuse holders and switch-fuse equipment in industrial distribution systems.
