Contactor Interlocking Wiring:

This diagram shows how to make contactor interlocking wiring. In this circuit diagram. We use a total of 2 magnetic contactors, a stop switch, a forward switch, and a reverse push switch. This diagram is very easy to connect. If you want to see how to connect the circuit please check our youtube video link in the below post. Please be sure you have good knowledge about electricity otherwise any mistake can be a hazard to your life.

Components used to make the Contactor Interlocking Wiring:

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. Push 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.

Frequently asked questions

What is interlocking in the motor?

To interconnect the motor circuit in such a way, in which the second motor will not start until the first one runs likewise the third motor will not run unless the second one runs, and so on. This kind of motor circuit Diagram connection is called interlocking.

What is interlock in a starter?

Automatic transmissions are usually equipped with a starter interlock system. This serves the purpose that a vehicle can only be started when a selector lever, actuatable by the driver, is in a neutral or parking position. Starting the vehicle in a driving position, e.g. R or D, is hereby prevented.

What is the electrical interlock between two motors?

What is Electrical Interlocking? To interconnect the motor circuit in such the simplest way, during which the second motor won't begin till the primary one runs likewise the third motor won't run unless the other runners and then on. this sort of motor circuit affiliation is called interlocking.

Why interlocking blocks?

Fast and easy to assemble without fixing materials. It is flexibility makes it an ideal solution for both permanent and temporary storage of structures. The interlocking concrete of the blocks allows you to easily construct the solution you desire. Cost-effective, premium quality, and with proven reliability.

What is the size of the interlocking?

The size of the interlocking brick is 125 mm x 250 mm x 100 mm and the diameter of the reinforcement bar (rebar) used is 12 mm. The dimensions of the interlocking brick beam are 2130 mm in length, 125 mm in width, and 300 mm in height.
