The ABB A145-30-11-87 is a three-pole contactor from the A145 series, rated for 440 V applications. Its official lifecycle stage is marked as eol_hot, which means the manufacturer has issued a notification that production will end — this part is in its last-time-buy window or very close to it. For procurement, that translates to a limited sourcing window: once existing distributor stocks and the manufacturer's final production run are exhausted, the part will only be available through independent surplus and broker channels. Because the eol_hot status is active now, any new BOM that carries this order code should plan for a substitute or bridge buy.
Where this contactor class fits in a panel
A three-pole contactor like this one is the standard building block for switching three-phase motor loads, resistive heating banks, and other power circuits in industrial control panels. The A145 frame size places it in the mid-range of ABB's contactor line, handling motor currents up to roughly the 145 A class in AC-3 duty — a common fit for pumps, compressors, and conveyors in the 30–75 kW range depending on voltage.
