actually the torque produced by the interaction of the two magnetic fields produced by potential coil and current coil of a reverse power relay is proportional to the product of voltage and current sensed by the relay and also dependent on the relative polarity of the two quantities, so under normal operating condition suppose torque acts in clockwise direction,then if only polarity of current changes torque created will be acting counterclockwise direction creating trip of the circuit breaker.
