Today I am here to share with you the 3 phase submersible pump wiring diagram. In which I control a three phase submersible pump motor using magnetic contactor. Not only a contactor but also I install the thermal overload relay which will protect the motor form burning in case of over current flow to the circuit. In the diagram I showed the 3 Pole MCCB breaker, magnetic contactor , thermal overload protection relay, and normally open, normally close push button switches. 3 phase submersible pump motor and electric wiring connection. This will be the complete guide of controlling a three phase submersible pump motor using magnetic contactor.
3 Phase Submersible Pump Wiring Diagram Explanation Complete Guide
Before I explain the diagram. I want to write about the device and things in this circuit. In Circuit first we use the MCCB breaker. (Module Case Circuit Breaker)
We used a three pole MCCB circuit breaker in the diagram. This circuit breaker will control the all substances use in the circuit and we can switch on/off the electric power supply by using the three pole circuit breaker. In the diagram I did not control the neutral wire. However if you want to control the neutral (N) black wire then you must use the 4 pole circuit breaker.
The next thing which used in the circuit is the magnetic contactor. Basically a contactor is a type of relay which we can use for different works. However if you want to learn more about the magnetic contactor basic explanation then the below guide is for you.
The push button switches which used in the circuit is NC and NO switches. The normally open contacts switch will be use for starting the motor. And normally close contacts push button switch will be used for switch off the motor or load.
The next device which use in the below 3 phase submersible pump wiring diagram is a thermal overload relay. Which we use to protect or switch off the motor or load during over current flow. This device is available in different shapes and different values according load. In thermal overload protector we have move able ampere adjustable. From which we can setup the ampere or load level.
