ABB 1SCA022627R7830 OFAF4H1250 HRC Fuse Link 1250A 500VAC/250VDC 120kA 4-Pole

The ABB OFAF4H1250 HRC fuse link (SKU: 1SCA022627R7830) is a high-rupturing-capacity fuse designed for demanding industrial power distribution and overcurrent protection applications. Rated at 1250A with a maximum voltage of 500V AC / 250V DC and an exceptional breaking capacity of 120 kA AC (70 kA DC), the OFAF4H1250 delivers reliable fault protection in control panels, switchgear, and motor circuits where high short-circuit currents must be safely interrupted.
