Why Choose the ABB OFAF2H250 DIN Fuse Link?
The ABB OFAF2H250 is a high-rupturing-capacity DIN-type gG fuse link designed for dependable protection of cables, conductors and general-purpose industrial electrical circuits against overload and short-circuit currents. Part of the ABB OFAF fuse range, it combines a 250 A rated current, 500 V AC rated voltage and NH2 / IEC size 2 construction.
The gG utilisation category provides full-range protection, allowing the fuse link to protect electrical circuits against both overload and short-circuit conditions. This makes the OFAF2H250 suitable for industrial power distribution, switchgear, control panels and other installations requiring reliable high-current circuit protection.
With its standard DIN/NH blade-contact format, the OFAF2H250 integrates into compatible fuse bases, fuse switches and switch-disconnectors. Its size 2 construction also incorporates dual indication, providing convenient visual indication of fuse operation in industrial installations.

Reliable Full-Range Industrial Circuit Protection
The ABB OFAF2H250 uses a gG operating characteristic designed to provide full-range protection against overload and short-circuit currents. When excessive current flows through the protected circuit, the fuse element operates to interrupt the fault and help protect cables, conductors and connected electrical equipment.
Its standard NH2 format makes the OFAF2H250 suitable for integration into industrial low-voltage distribution equipment. The combination of a 250 A current rating, 500 V AC capability and robust HRC construction makes it well suited to demanding power distribution and machinery installations.
Typical Applications
- Industrial low-voltage power distribution.
- Electrical switchboards and distribution panels.
- Industrial machinery and control systems.
- Fuse switches and switch-disconnectors.
- Cable and conductor protection.
- Commercial and industrial electrical installations.
