Reliable Full-Range Industrial Circuit Protection
The ABB OFAF2H300 uses a gG operating characteristic designed to provide full-range protection against overload and short-circuit currents. When excessive current occurs, the fuse element interrupts the circuit to help protect cables, conductors and connected electrical equipment from damage.
Its 300 A rating and standard NH2 construction make the OFAF2H300 well suited to higher-current low-voltage distribution systems. The fuse can be installed in compatible DIN/NH fuse bases, fuse switches and switch-disconnectors used throughout industrial electrical 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.
