    It will not work. The relay checks for phase relationship. If all two/three are the same phase it shuts off. three phase must be 60 deg apart plus minus some x degrees factor.

    There is also current factor which must be met.

    unclear (as all of your questions are) what you are asking. If you short the three phases together, you will cause breakers to pop or fuses to blow, due to the high currents that result. Or a fire.
