Reliable Full-Range Industrial Circuit Protection
The ABB OFAF2H400 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 400 A rating and standard NH2 construction make the OFAF2H400 suitable for high-current low-voltage distribution systems. The fuse link can be integrated with compatible DIN/NH fuse bases, fuse switches and switch-disconnectors in 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.
