The ABB OFAFC00GG125 is a high‑rupturing‑capacity (HRC) DIN‑type fuse link used for overcurrent protection in low‑voltage electrical systems. It is part of ABB’s range of gG full‑range protective fuse links, designed to safely interrupt both overload and short‑circuit faults in distribution and industrial circuits. The fuse link is installed into a compatible fuse holder or switch‑fuse (e.g., ABB OS or OT series fusible disconnects) to protect conductors, switchgear, transformers, and other electrical components. This fuse element provides fast and reliable clearing of fault currents while limiting let‑through energy to reduce damage to equipment and maintain selectivity in power systems.
