Which outcome results when three-phase breakers trip asynchronously in a motor circuit?

A)Motor single-phasing and overheating
B)Balanced voltage resumes immediately
C)Reduced motor starting torque
D)Harmonic currents remain unchanged

💡 Explanation

Asynchronous tripping causes motor single-phasing, because the motor then operates on only one phase, producing excessive currents in the remaining windings. Therefore, overheating occurs rather than maintained balance where all phases remain active with normal voltages.
