2 way switch control in 3 phase motor:

This diagram shows how to make a 2-way switch control in 3 phase motor. In this circuit, we use a TP MCB ( Tripple Pole Miniature Circuit Breaker ), two 2 way switches, two magnetic contactors, and two 3-phase motors. This circuit is very simple and easy to make. If you want to know more about this circuit please stay with our website, and check our youtube video below the post.

Components used to make the 2 way switch control in 3 phase motor:

01. 3 Phase Motor:

A Three-Phase electric motor uses a 3-Phase Power Supply to Convert Electric Energy into Mechanical Energy. It contains four Wires (Three hot Wires and one Neutral Wire) and Uses 3 Alternating Currents of the Same Frequency. Since it Generates a Rotating Magnetic Field, it does not need a Capacitor for the Startup. Some Three-Phase Motors are Reversible, Which Means they can serve as Generators by Turning Mechanical Energy into Electrical Energy.

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. 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.

04. SPST Switch:

An SPST (Single Pole Single Throw) Switch is a Switch That only Has a Single Input and can Connect Only to one Output. This means it Only Has one Input Terminal and Only one Output Terminal. A Switch is a Mechanical or Controlling Device That Changes the Flow of Current Direction or Interrupts the Flow of Current Within a Circuit. Single Pole Single Throws (SPST) is Perfect for on-off switching. When the SPST is closed, the Circuit is Closed and the light from the lamp switches on. When The Single Pole Single Throw (SPST) is then opened, the light from the lamp goes out and the Circuit is off.
