Why Choose the ABB OFAA1GG100 100 A gG DIN Fuse?
The ABB OFAA1GG100, ABB order code 1SCA022700R9950, is a DIN-type HRC fuse link designed for general-purpose protection of cables, conductors and electrical equipment. Rated at 100 A, this fuse uses the NH1 / DIN size 1 format and the gG full-range fuse characteristic.
With a rated voltage of 690 V AC / 400 V DC, the OFAA1GG100 is suitable for demanding industrial distribution and power-control systems. Its gG utilisation category provides full-range protection against both overload and short-circuit currents when correctly selected and coordinated with the protected circuit.
The OFAA1GG100 incorporates dual indication to assist with fuse-status identification. Manufactured for industrial DIN-type fuse systems, it has a rated power loss of approximately 9.4 W, a net weight of approximately 0.28 kg and is supplied in a delivery batch of 3 pieces.
