Magnetic Contactor Interlocking:
This diagram shows how to make magnetic contactor interlocking. In this circuit diagram, we use 2 magnetic contactors, 2 DP MCBs ( Double Pole Miniature Circuit Breaker ), a NO switch ( Normal Open ), an NC switch ( Normal Close ), and a single-phase motor. This circuit is very simple and easy to make. If you want to know more clear details about this circuit diagram please check our youtube video below the post.

Components used to make the Magnetic Contactor Interlocking:
01. 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.
02. Power Generator:
An electric generator is a type of Electrical device that converts mechanical energy or power into electrical energy or power. However, dynamo generally refers to generators only. The first generator built was called a dynamo. This electrical device makes this conversion using the principle of kinetic electromagnetic energy generation. According to Farad is principle of electromagnetic induction, a dynamic electromagnetic induction is induced in a conductor when it passes through a magnetic flux.
03. DP MCB:
DP MCB In 2 Pole MCB, switching & protection is affected in phases and the neutral. A Double Pole or DP Switch is a Switch that Controls 2 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 2 Different Electrical Circuits at the same time, which allows the Appliances to Isolate safely and reliably. Fan or light Combinations and Medical Equipment are some of the many applications for DP Electrical Switches and Electrical components.
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 2 contacts when held in. When the button is released, the Circuit is broken. This type of Switch is also known as A Normally Open (NO) Switching system. 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:
An NC (Normally Closed) Push Button is a Push Button That, In Its Default State, Makes Electrical Contact With The Circuit. An NC (Normally Closed) Push Button is a Push Button that, in its Default State, Makes electrical Contact With the Circuit. When The Button Is Pressed Down, The Switch no Longer Makes Electrical Contact And The Circuit is Now Open. When The Button is Not Pressed, Electricity Can Flow, But When it is Pressed The Circuit is Broken. This type Of Switch is Also known As a Normally Closed (NC) Switch.
06. 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 3-phase Motor, Including an AC Winding That is Placed on The Stator And Short-Circuited Conductors That are Placed in a Cylindrical Rotor.

Frequently asked questions
A magnetic contactor is an electrical switching device. It is used for switching an electrical circuit diagram on and off. It is a special type of relay but there is a basic to the difference between the contactor and a relay.
In general, magnetic contactors are the preferred choice for applications that require improved safety, smooth starting, overload protection, or easy control, while ordinary contactors are suitable for applications that are more focused on cost and simplicity.
Relays are used to control contacts of an electrical circuit diagram due to a change of parameters or conditions in the same circuit or any other associated circuit diagram. Contactors, on the other hand, are used to interrupt or establish connections in an electrical circuit diagram repeatedly under different conditions.
Problems with contactors manifest in three forms: (a) the contactor does not close, (b) it will not open, or (c) it flashes over. together when heat is applied. Over a long period of time, any movement can result in sufficient damage to the coil to cause an insulation breakdown.
Transients, voltage, and frequency fluctuations couid cause the coil to get damaged. A corrosive environment that contains damaging chemicals or vapors can also cause damage to the contactor coil. Mechanical shock or excessive vibration could also cause contactors to fail.
