Contactor interlock wiring diagram - Motor Control Sinhala / Electrical wiring

This video about Contactor interlock wiring diagram - Motor Control Sinhala / Electrical wiring
This video will explain how to do interlock wiring using two contactors.
two contactor interlocking.
easy way magnetic contactor interlocking diagram connection.
Magnetic contactor are used in the electric motors to balance the change in frequency of the motor or the state of the motor which can be termed as the switching of the motor from on and off state. magnetic contactor act as a safeguard to protect the power supply and the motor.
why interlocking is used for the contactors?
A technique called interlocking is used to prevent the contactors from being energized simultaneously or closing together and causing a short circuit. this interlock locks out one contactor at the beginning of the stroke of either contactor to prevent short circuits and burnouts.
A technique called interlocking is used to prevent the contactors from being energized simultaneously or closing together and causing a short circuit.
An interlock is a feature that makes the state of two mechanisms or functions mutually dependent. It may be used to prevent undesired states in a finite-state machine and may consist of any electrical, electronic, or mechanical devices or systems.

How to interlocking in electrical system?
what is interlocking ?
working principal of contactor, different parts and finally power and control wiring diagram of contactor, connection of contactor along with its specifications are explained in a very simpler way. This is the most commonly used component in electrical power.
A contactor is a device that is for making and breaking an electrical power circuit. For example, we usually use a contactor for turning on and off an electrical motor.
A relay works the same way as a contactor. That means a relay also has a coil and some contact. When the coil is energized, the contacts will close.
But here is the difference... a relay is usually used for smaller devices with lower current and voltage rates. A contactor, however, is used for bigger devices with higher current and voltage rates.
- When you press the start switch, the coil will be energized, the contacts will be closed and the motor will be turned on.
- When you press the stop switch, the coil will be de-energized, the contact will open and the motor will turn off.
