Reliable Protection for Low-Voltage Electrical Circuits
DIN-type gG fuse links provide full-range protection against overload and short-circuit currents. When excessive current passes through a protected circuit, the fuse element operates to interrupt the fault current, helping protect cables, conductors and connected electrical equipment against potentially damaging electrical conditions.
The ABB OFAF2H50 combines a 50 A current rating with a standardised DIN size 2 format, making it suitable for industrial switchboards, distribution panels and other low-voltage installations. Its gG characteristic provides versatile protection across a wide range of general electrical distribution applications.
Typical Applications
- Low-voltage electrical distribution systems.
- Industrial switchboards and distribution panels.
- Cable and conductor overcurrent protection.
- Electrical machinery and automation equipment.
- Fuse switches and fuse bases using compatible DIN size 2 fuse links.
