The ABB EHDB280C2P-1L2S is a 2-pole disconnector rated for 280 A continuous current at 120/60 VAC, with a 2/2 contact configuration and surge-rated construction. It's the kind of part you'd find in a panel isolating a motor feeder or a branch circuit where you need a visible-break disconnect with surge withstand capability. The 280 A rating covers the full-load current of a motor or resistive load bank. The 2/2 contact arrangement provides two main poles plus two auxiliary contacts for status feedback or interlocking.
Mounts on standard DIN rail — the 2-pole footprint fits a 36 mm wide module. The 280 A rating means the incoming cable is likely 70–95 mm²; verify the terminal lug range against the panel gland plate before wiring. Surge-rated construction implies internal MOV or gas-tube protection; no external surge suppressor needed at the disconnect point.
