3 phase star 3 motor connection:
This diagram shows how to make 3 phase star 3 motor connection. In this circuit diagram, we use a TP MCB ( Tripple Pole Miniature Circuit Breaker ), a DP MCB ( Double Pole Miniature Circuit Breaker ), an NC switch( Normal Close ), 3 NO ( Normal Open ) Switches, 3 Magnetic Contactors with overload, and 3 Three-Phase Motor, etc. This diagram is very simple and easy to make.

Components used to make the 3 phase star 3 motor connection:
01. TP MCB :
The full meaning of MCB is Miniature Circuit Breaker. MCB is an electromagnetic switch or device. If for any reason a short circuit occurs in the supply line or load line (line to line or line to neutral) or in case of overload, the MCB automatically trips and disconnects the main line circuit or household power Connection. TP MCB In Three Pole MCB, Switching & Protection is affected in only Three-Phases and the Neutral is not part of the MCB. 3 pole MCB signifies the Connection of Three Wires for a Three-Phase system R-Y-B Phase. Three-Phase Supply Only Without Neutral.
02. 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.
03. 3 Phase Motor:
The Meter Which is used for Measuring the Power of 3 Phase supply is known as the 3-phase energy meter. A 3-phase Energy meter is a Three-phase 4-wire direct Connected meter that is Used to estimate the electricity on the Three-phase power supply, mostly for residential & commercial use. A Three-phase meter helps consumers & utilities in revenue protection. It Provides Data Storage and Communication Facilities as well. The 3-phase meter is Constructed by Connecting the two single-phase meters through the shaft.
04. 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.
05. NC 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. 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.
07. Overload Relay:
Overload Protection is Protection Against a Running Overcurrent That Would Cause Overheating of The Protected Equipment. Hence, An Overload is Also a Type of Overcurrent. Overload Protection Typically Operates on an Inverse Time curve where the Tripping Time Becomes less as the Current Increases. This Overload Protector is an Essential Component for Many Sockets. The Top-Quality Overload Protector can Effectively Protect Electrical Products from Power Surges.
