Why Choose the ABB OFAA00GG80 80 A gG DIN Fuse?
The ABB OFAA00GG80 is a DIN-type HRC fuse link designed for general-purpose protection of cables, conductors and electrical equipment. Rated at 80 A and 690 V AC, this exact fuse uses the NH00 / DIN size 00 format and the industry-standard gG full-range fuse characteristic.
The gG utilisation category provides full-range protection against both overload and short-circuit currents when the fuse is correctly selected and coordinated with the protected circuit. This makes the OFAA00GG80 suitable for industrial distribution systems, machinery, switchboards and other applications requiring dependable high-rupturing-capacity fuse protection.
The OFAA00GG80 is rated for 690 V AC / 250 V DC operation and incorporates dual indication for convenient fuse-status identification. Manufactured to IEC 60269, it has a power loss of approximately 6.8 W and a net weight of approximately 0.18 kg.
