PRACTICAL INSTALLATION of the PHASE LOSS RELAY with Diagram Today we are going to talk a little and demonstrate an installation of this guy here.. THE PHASE LOSS RELAY, do you know it, have you heard of it? Did you know that an air conditioner, a MOTOR, can burn out due to the lack of a phase? If a phase is missing in the circuit, you can lose a motor or several motors. This PHASE LOSS RELAY model is to be installed on a DIN rail, right next to the control circuit of your motor (ALONG with the circuit breaker, contactor), I chose this model from WEG (Model RMW17-FF) In this video, we show the importance of using single-pole circuit breakers when installing the PHASE LOSS RELAY. Because it provides a simulation of a phase failure during maintenance, we can diagnose a possible defect in the device, and then we can install a BIPOLAR OR TRIPOLAR circuit breaker for the load, that is, the motor. (according to the voltage of each equipment)
