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.

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

01. 3 Phase Motor:

A 3-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 3-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 3-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 for TP MCB. 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 MCB. the MCB automatically trips and disconnects the main line circuit or household power supply Connection. TP MCB In 3 Pole MCB, Switching & Protection is affected in only 3-Phases and the Neutral is not part of the MCB. 3 pole MCB signifies the Connection of Three Wires for a 3-Phase system Red-Yellow-Blue Phase. 3-Phase Supply Only Without Neutral.

04. 2 way Switch:

The 2-Way Switch has a wire connection system. It is a type of switch that has three wire connections. And it really has no off or on. Both sides can be turned on or off depending on how you connect one to the other. The connection of the two-way switch is different. If you use it as a changer, then put the load in the middle one and two separate lines in the upper and lower ones. The two-way switch is a type of multiway switch. Multiway switches have more points and can be controlled in multiple ways simultaneously.

Frequently asked questions

What is a 2-way switch called?

A SPDT is called a two-way switch in the European Union, and a three-way switch in North America. A SPDT switch has 3 terminals. It will have 1 terminal in and 2 terminals out. Each terminal on a SPDT switch has a name. The input terminal is called Common.

What is the difference between 2 way and 3 way switch?

Much like the 2-way switch, a three-way switch turns a light on and off. However, there is a crucial difference. The three-way switch is used in conjunction with another three-way switch. Each 1 of them has a power supply to interrupt the electrical flow or turn the light off from a different part of the room.

How to convert a 2-way switch to a 1-way?

Most 2-way switches have a Common terminal, as well as an L1 or L2 terminal. For two-way switching, you will need to connect both L1 and L2. For 1-way switching, as you have 1 less connection, you only need to use the L1 connection. You could leave the L2 connection blank.

Why is a 3-way switch not called a 2-way?

The name originates from the fact that there are 3 possible ways to wire the switches together to control the light. This includes the ability to turn the light on or off from either location, as well as the option to have the light on at one switch and off at the other.

Why does my 2-way switch have 3 wires?

The term is slightly confusing as the system will actually include 3 wires. However, the 3 wire, which typically has a green/yellow sleeve is the Earth wire. The Earth is a very important part of the electrical system and all switches, appliances, or lights must be correctly earthed.
