What the 220 A rating means for fit
The Eaton EHDB220C-1 is a 3-pole definite purpose contactor rated for 220 A continuous current, with a 120/60 VAC coil and lug-type terminals. The 220 A figure is the continuous current rating under the manufacturer's duty cycle — it governs the maximum resistive or motor load the contactor can switch without exceeding its thermal rise limits. For a 3-pole contactor at this current level, the part is sized for heavy compressor, pump, or HVAC condenser loads where a general-purpose contactor would be oversized or lack the required SCCR coordination.
