Which outcome occurs when a three-phase motor's control circuit loses one phase feeding to the magnetic contactor coil?

💡 Explanation

When one phase is lost in the control circuit, the magnetic contactor may chatter or drop out, repeatedly disconnecting and reconnecting the motor, or the contactor might weaken and cause single-phasing across the motor windings which can lead overheating. Therefore, single-phasing overheating results, rather than transformer failure, motor reversal, or VFD damage, which would require distinct conditions.
