275 A across the line
The ABB A185-30-11-51 is a 275 A, 480 V AC coil, three-pole non-reversing contactor with one normally-open and one normally-closed auxiliary contact built in. Non-reversing means it switches motor loads in one direction only — no interlocking for forward/reverse pairs is built into the contactor itself.
End-of-life sourcing reality
This contactor is flagged at the eol_hot lifecycle stage — the manufacturer has ended production, and remaining stock is moving through surplus and independent channels.
