Friends, you must have seen this type of electrical device installed in many electrical panels. We call this electrical device as MPCB, the full form of which is Motor Protection Circuit Breaker. This device is a protection device. This means that if you want to protect our motor, for example, our three phase motor, then you can use this device, as you know, We have a motor. If too much current goes into that motor, then in this condition our motor can burn or get damaged. For its protection, we often use this type of over and relay, but if you want, you can use the over and relay. In place of this device, you can simply use this device. The working of both the devices is the same, which means that this device also protects your motor from over current and from short circuit. Apart from this, it is same from single phase. There is MPCB, this MPCB also provides us protection from overload circuit and single phase. For example, if you have a motor like this, if three phase power is being supplied to that motor then suddenly one phase gets switched off. If there is a power supply, then if it goes out, in this condition our MPCB will immediately rip and will stop the motor. Similarly, you will see that in the MPCB, you get the option to set the current, just like you get here in the overload relay. There is an option to set the current. Similarly, in MPCB also you will get the option to set the current. At this point, if you want, you can set the current by rotating it here. Apart from this, you can use MPCB. The benefit is that if we want to start or stop our motor, then we can start it from here, for example, if we press the start button, our motor will start and if we want to stop it, then You can stop it by pressing the stop button, which means that in overall and relay, we do not get such an option that we can start and stop the motor through it, which means that if you have a motor like I will show you here, mine. Is there a book? It has been told in this book that if we have to directly control the motor we have, we do not want to put a complete push button here, put a contractor and switch it on and off through it, then we can simply use MPCB here. We can start the button which is given in the MPCB. If we press this button then the motor will start and on pressing the stop button the motor will stop. Now in this MPCB, you will get a test button here like I have also told in my book that in the MPCB, you are provided with a test button through which you can check the MPCB. Even in the overall delay, you get the option of test here as I will show you. So, Pay Test is written here, we have to scroll like this, to check, we have to side here, similarly, you will get the Pay Test button here in MPCB, if you scroll like this, If you scroll it on the left side, then our MPC also gets tripped immediately, that is, through this we can check it, like as an example, I have turned it on, after turning it on, if I turn it to this side. Here you will see that it has tripped, which means that my MPC is also in working condition. Okay, this is the basic overview about MPCB. Now if you want to do the wiring of this MPCB, then simply follow this wiring diagram. You can use: If you have to directly connect the MPCB with the motor, then what you have to do is simply provide three phase power supply to your MCB. After providing three phase power supply, output power supply. Whatever is there will have to be taken and connected to the input terminal of the MPCB. The input terminal is mentioned here by the name of l1 l2 l3 or if you want, the terminal numbered 1 3 5 is mentioned on it i.e. three phase power supply. You can connect, after this you will get the terminal with the name of t1 t2 t3 through which the power supply goes to your motor, similarly in the over and relay also you get the same type of terminal, this is ours. l1 l2 l3 and here where t1 t2 t3 t1 t2 t3 is written, it means that from this point the power supply will go to the motor. Similarly, the terminal number is mentioned here, the same is same in both. Now friends, if you want to use this MPCB for a single phase motor, as mentioned here, if our motor is single phase and if we want to use MPCB, then there is no such condition. The connection that will be made will be a little different as I told you a little while ago that MPCB provides us the protection of single phase also, if we only pay phase supply here, l1 is phase supply and l3 is neutral. The supply was given and from the output we took the phase and neutral supply and connected it to the motor. If we start the MPCB, it will trip immediately, which means it will not allow the motor to start. In this condition, you will not get any power in the MPCB. Wiring has to be done in a slightly different type, how will you do the wiring, see here which is our next page, it is explained in this page, as you will see, this is a single phase motor, in this motor you will see that there is already a capacitor installed here. Capacitor is attached with the motor. Now to operate this motor, we have to provide only phase supply and neutral supply. So for this, what we will do here is take a single phase MCB with which phase supply and neutral supply are connected. Now, we took the phase supply and connected it to one terminal, you can connect it anywhere l1, l2, l3, you can connect it anywhere, it is not going to make any difference, so what did we do? We took the phase supply and connected it to the l1 terminal. Now the power supply we will get from T1 terminal does not have to be connected directly with the motor. What we have to do is to take the power supply from this point, rotate it and bring it back to the second terminal. Why is this because here There are three poles, there should be equal flow of power supply from all three poles, which means that which is our MPCB, the current flow should flow from all the three terminals of this MPCB in equal quantity, only then our motor will work, that is, it will run, so if you If you want that the MPCB should not trip, then what will you do for this, you will get the output of the phase supply which you have connected on the first terminal, then take the power supply from this point, rotate it and give it to the second terminal and then on l2. From here the power supply has to be taken to the motor, which means that all the terminals of the MPCB have to be used. Now here you have only single phase power supply, then you have to rotate the single phase power supply and go back to the second terminal. Then the output of the second terminal will be the power supply. Here it means that at t2, the power supply has to be taken from that terminal and connected to the motor. You take the neutral supply and connect it directly, if you make the connection in this way. So your MPCB will not trip at all and will work normally. Now if there is any fault in the motor or overload, then in this condition your MPCB will trip. Okay, now this MPCB is about this MPCB.

Apart from this, we have many courses which are going to be very helpful for you, like the current course on PLC of Siemens company is How to Read Electrical Panel Diagram, which diagrams of the panel. How to read it? If you want to learn it, then its course is also available. Apart from this, you will see here about BFD, PLC, electrical wiring, basic motor starter. Apart from this, there are other courses which you can join and it will be very good for you. You can get the knowledge. Now friends, let me tell you a little about the overall relay here. As you know, what is the overall relay, we use it for the protection of the motor. In the overall delay, if you look, you will see here. Power terminal is available on it, apart from this, some control terminals are also available, you will get its details here, as you will see that there is an overall relay, we make the symbol of that overall relay in this way and in the overall relay, you will get it here. You get the terminal number 9596, the terminal number 95 and 96 are the NC contact and here the terminal number 97 and 98 are our ANO contact. Now in the overall relay which is there, I told that the one which resets. Or there is also a test button which is shown here, if we press it then the overload relay gets tripped through which we come to know whether the overload relay is working or not. Apart from this, there is a reset button in the overall relay. If we press it, our overall relay gets reset. In some of the overall relays, you also get a stop button like the one given here. We will press this stop push button, otherwise our motor will stop. Let me explain to you a little bit how it stops. See what happens, which is our control circuit diagram of dual starter as I show you here. By opening the circuit diagram of dual starter, in this circuit diagram you will see that the NC contact of the overall and relay has been used here. This overall relay which is here with terminal number 9596 has been used here. Now if I go here If I press the stop button, what will happen? This contact gets opened and due to its opening, the power supply that was flowing from here will be cut due to which this contractor will not be able to get power supply. And if this contractor is off, then in this condition there will be no power supply flow in this circuit due to which our motor will stop. Okay friends, I hope that you liked today's video.
