Why Choose the ABB OFAA000GG4 4 A HRC Fuse Link?
The ABB OFAA000GG4 is a 4 A gG HRC DIN fuse link designed for general-purpose protection of low-voltage electrical circuits. Identified by ABB product ID 1SCA022661R8330, this compact NH000 / DIN size 000 fuse link is rated for operation at up to 690 V AC.
Its gG utilisation category provides full-range protection against overload and short-circuit currents, making the OFAA000GG4 suitable for protecting cables, conductors, distribution circuits and industrial electrical equipment. ABB's HRC construction provides rapid fault clearing and strong current-limiting performance during short-circuit conditions.
The OFAA000GG4 combines its compact NH000 format with a power loss of approximately 1.5 W at rated current. Its established DIN fuse-link design makes it a practical choice for industrial fuse bases, switch-fuse equipment, machinery and low-voltage distribution assemblies.

Full-Range Protection for Low-Voltage Circuits
A gG fuse link provides general-purpose full-range protection, covering both sustained overload currents and high short-circuit currents within its specified operating range. The ABB OFAA000GG4 can therefore protect cables, conductors and electrical equipment against the principal overcurrent conditions encountered in low-voltage distribution systems.
During a severe fault, the HRC fuse element interrupts the current rapidly and provides current-limiting action, helping reduce the thermal and electrodynamic stresses imposed on downstream equipment. The compact NH000 construction makes the OFAA000GG4 particularly suitable where dependable 4 A protection is required within industrial fusegear and control panels.
Typical Applications
- Industrial power distribution circuits.
- Electrical control panels.
- Machine and automation systems.
- Cable and conductor protection.
- Fuse-base and switch-fuse assemblies.
- Commercial and industrial low-voltage installations.
