Single phase motor starter connection:

This diagram shows how to make a single-phase motor starter connection. In this circuit, we use a DP MCB ( Double Pole Minature Circuit Breaker ), an RCCB ( Residual Current Circuit Breaker ), a magnetic contactor, a single-phase motor, a NO Switch, and a flowmeter. First, we need to connect the DP MCB with the power source, then connect the RCCB with the DP MCB, then connect the contact with the circuit, then connect the NO switch, flowmeter, and the motor with the single-phase motor.

Components used to make the Single phase motor starter connection:

01. DP MCB:

DP MCB In Two Pole MCB, switching & protection is affected in phases and the neutral. A Double Pole or DP Switch is a Switch that Controls two Circuits at the same time. In terms of Residential Switching, this Normally means it Switches the live and Neutral at the same time. In Layperson Terms, Double Pole switches or DP Switches are Exclusively Designed to Control two Different Electrical Circuits at the same time, which allows the Appliances to Isolate in a safe and reliable manner. Fan or light Combinations and Medical Equipment are some of the many applications for DP Electrical Switches.

02. RCCB:

The Residual Current Circuit breaker RCCB is the Safest device to detect and Trip against Electrical Leakage current, thus Ensuring Protection against Electric shock Caused by indirect contact. Circuit breakers are automatically Operated Electrical Switches that Protect Electrical Circuits from Short-Circuiting or Overloading. It Protects against many major accidents. RCCB Circuit Breaker is an Electrical Wiring device whose function is to disconnect the current in the circuit.

03. Magnetic Contactor:

A magnetic contactor is an electromagnetic switching device. It is generally used for controlling three-phase motors. The operation of a magnetic contactor is similar to that of a relay, but a relay is used for low-power or low-voltage connections, and a magnetic contactor is used for high-power or high-voltage connections. As soon as the supply is applied to the magnetic contactor coil, its normally open contacts are closed and normally closed contacts are opened and the associated devices are also operated. This is how a magnetic contactor works.

04. Single Phase Motor:

A Single-Phase Motor is an Electrically-Powered Rotary Machine That Can Turn Electric Energy into Mechanical Energy. It Works by Using a Single-Phase Power Supply. Single-phase Motors Are Used in Equipment And Machines That Are Smaller in Size And Require Lower Horsepower. This Includes Equipment Such As Refrigerators, Pumps, Compressors, Fans, and Portable Drills. Single-Phase Motors Have a Similar Construction to The Three-Phase Motor, Including an AC Winding That is Placed on The Stator And Short-Circuited Conductors That are Placed in a Cylindrical Rotor.

05. NO Switch:

NO (Normally Open) Terms Refer to a Type of Dry Contact or Wet Contact. A ‘Push to Make’ Switch Allows Electricity to flow Between its two contacts when held in. When the button is released, the Circuit is broken. This type of Switch has also known as A Normally Open (NO) Switch. As its name implies, a Normally Open (NO) Switch Contact or “a Contact” is a Switch. Put very simply, a Normally Open Sensor will have no Current When in a Normal State But When it Enters an Alarm State it will have +5V applied to the Circuit.

06. Flowmeter:
