Reliable Full-Range Protection for Electrical Circuits
gG fuse links such as the ABB OFAF0H25 provide full-range circuit protection against both overload and short-circuit conditions. When excessive current reaches the fuse operating threshold, the fuse element interrupts the circuit to help protect cables, conductors and connected electrical equipment from damaging fault currents.
The OFAF0H25 combines a 25 A current rating with a 500 V voltage rating and DIN size 0 construction. Its standardised format and dual indication make it suitable for industrial switchboards, distribution equipment, machinery and control systems where dependable and maintainable fuse protection is required.
Typical Applications
- Industrial low-voltage electrical distribution.
- Switchboards and distribution panels.
- Cable and conductor protection.
- Industrial machinery and automation equipment.
- Fuse switches and switch-disconnector assemblies.
- Electrical control panels and commercial installations.
