The new type submersible pump starting protector is composed of a three-phase power supply A, B, C, a leakage protection circuit, an over-voltage protection circuit, an overload protection circuit, an execution circuit and a motor to be protected. One end of the leakage protection circuit is connected to a three- The other end is connected with the execution circuit; one end of the leakage protection circuit is connected with the three-phase power supply, and the other end of the leakage protection circuit is connected with the execution circuit; the output of the execution circuit controls the motor to be protected. The device uses A, B, C three-phase AC power supply into the leakage protection circuit and over-voltage protection circuit and the implementation of the circuit structure, with a large current, less components, low cost, simple circuit, good function, practicality and so on advantage.
