Abstract
Phase protector for three phase motors, characterized by consisting of two similar zones with alternating input transformer on the network, so that when a phase is missing, the corresponding relay or contactor will be deactivated and, thus, the power contact circuit is opened leaving the motor to run so that, when the phase is reset, the relay is activated and the motor starts again, except in the case that it is grounded, lowering the voltage below normal, at which point it would enter in action an automatic circuit of any of the zones, cutting off the supply voltage of the relay and deactivating the force contactor, not letting the motor run.
