ABB A9-22-00-34 A9 4P Contactor, 175/50 A, EOL Hot

The 175/50 A rating on this 4-pole contactor likely reflects a dual duty — 175 A in AC-1 resistive load and 50 A in AC-3 motor switching (the typical derating for inductive motor loads). That makes it sized for moderate motor control or heavy resistive heating in a panel. The A9 series uses a standard DIN-rail footprint, so it clips into the same enclosure slot as other ABB A9 components. No auxiliary contact block or coil voltage is specified in the listing, so verify those against your existing circuit before committing the BOM line.
