Auxiliary contacts are used to signal and control circuits, not to carry the motor load. The main contacts in a contactor are the ones that actually feed the motor, so they must handle high currents and the large inrush when the motor starts. That means the primary contacts are sized for much higher amperage. Because auxiliary contacts only switch smaller control currents, their rating is lower. So the statement is true: auxiliary contacts are typically rated at a lower amperage than the contactor’s primary contacts, aligning with their role in control rather than power handling.
