Why Choose the ABB OFAA000GG40 40 A HRC Fuse Link?
The ABB OFAA000GG40 is a 40 A gG HRC DIN fuse link designed for general-purpose protection of low-voltage electrical circuits. Identified by ABB product ID 1SCA022661R9140, 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 both overload and short-circuit currents, making the OFAA000GG40 suitable for protecting cables, conductors, distribution circuits and industrial electrical equipment. The high-rupturing-capacity construction provides dependable interruption and current-limiting performance under severe fault conditions.
The OFAA000GG40 has a rated breaking capacity of 80 kA AC and uses ABB's established DIN-type fuse-link construction with dual indication. Its NH000 format combines a 40 A current rating with compact dimensions for use in industrial fuse bases, switch-fuse assemblies and power-distribution equipment.

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 OFAA000GG40 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 thermal and electrodynamic stresses on downstream equipment. With an 80 kA AC breaking capacity, the OFAA000GG40 provides robust fault protection while its compact NH000 construction helps conserve space 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.
