Reliable Full-Range Protection for Electrical Circuits
gG fuse links such as the ABB OFAF000H63 provide full-range protection by responding to both overload and short-circuit conditions. When excessive current causes the fuse element to operate, the fuse interrupts the circuit to help protect cables, conductors and connected electrical equipment from the effects of damaging fault currents.
The OFAF000H63 combines a 63 A rating with compact DIN size 000 construction, making it suitable for space-conscious industrial fusegear. Its standardised DIN blade format supports installation in compatible fuse bases and switching equipment used in distribution panels, machinery and industrial control systems.
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.
