The utility model provides a phase changing device of a three-phase load automatic balancer. The phase changing device of the three-phase load automatic balancer aims to solve the technical problems that a breaker and the like for phase changing are arranged for single-phase loads due to three-phase unbalance hazards, but it cannot be guaranteed that power is supplied for a user continuously and reliably in the adjusting process. The phase changing device is characterized in that the phase changing device is composed of a main circuit and a transition circuit; a magnetic latching relay is in series with each phase line to form the main circuit; a transition relay is connected with each phase line, and output terminals of the transition relays are connected in parallel and then are in series with a transition resistor; and output terminals of the main circuit and the transition circuit are connected in parallel and then connected with an input terminal of a corresponding transition relay and an input terminal
