Why Choose the ABB OFAA1GG200 200 A gG DIN Fuse Link?
The ABB OFAA1GG200 is a high-performance HRC DIN fuse link designed to provide reliable overload and short-circuit protection in low-voltage industrial electrical installations. Identified by ABB order code 1SCA022701R0290, it forms part of the ABB 311002-Fuses And Fusebases product group and combines a 200 A current rating with the standard NH1 / DIN size 1 fuse format.
The OFAA1GG200 uses a gG full-range utilisation category, making it suitable for general-purpose protection of cables, conductors, distribution circuits and electrical equipment against both overload and short-circuit currents. Its HRC construction provides current-limiting performance during fault conditions, helping reduce thermal and electromechanical stress on protected equipment.
Rated at 690 V AC / 400 V DC, the OFAA1GG200 is suitable for demanding industrial power distribution applications. Its NH1 / DIN size 1 construction enables installation in compatible fuse bases, fuse holders and switch-fuse equipment, while dual indication provides convenient identification of fuse operation.

Reliable Protection for Industrial Power Distribution
gG fuse links such as the ABB OFAA1GG200 provide full-range protection against both overload and short-circuit currents. During an electrical fault, the fuse element interrupts excessive current to help protect cables, conductors, switching devices and connected equipment from potentially damaging thermal and electromechanical effects.
The OFAA1GG200 combines a standardised DIN size 1 format with a 200 A rating and high breaking capacity, making it suitable for coordinated protection within industrial switchboards, distribution panels and machinery. Its current-limiting characteristics can help reduce the energy passed through to downstream equipment during severe fault conditions.
Typical Applications
- Industrial low-voltage distribution systems.
- Electrical switchboards and distribution panels.
- Cable and conductor protection.
- Industrial machinery and production equipment.
- Power distribution and feeder circuits.
- Switch-fuse and fuse-switch assemblies.
- Compatible NH1 / DIN size 1 fuse bases and holders.
