00:00:00 - 00:05:00

This video explains how to use an electric thermal switch to protect a circuit. First, we press the accelerator pedal to see the movable piece of equipment color blue retreat, and open the main and auxiliary contacts. If we press the brake pedal, the movable piece of equipment returns to its original position, opening the main and auxiliary contacts.

• 00:00:00 In this video, I will explain how to make an enclosure for a contactor with march and stop, the necessary components for this circuit are as follows: an electric thermal switch for this case, and it is rated at 20 amperes; two pulse generators, one for march and one for stop, in this case, I use a green-colored pulse generator for march; connecting wires to these components, we find the following: an open/closed switch for the stop pulse generator, and a closed/open switch for the march pulse generator; finally, we have the contactor itself. In this video, I will explain the connection diagram for this circuit in detail, and I will use physical elements to show the circuit in action. First, I'll show the electric thermal switch in the left side of the video, and in the right side of the video I'll explain how to use physical elements to configure and operate the circuit. In this circuit, the protection circuit is the electric thermal switch. I'll use an electric thermal switch to protect the cables against overloading or short-circuiting. We'll connect the switch to the output of the phase-shifting relay, and we'll connect the relay to the open/closed switch
• 00:05:00 This video explains how to use a circuit breaker to protect a circuit. First, we press the accelerator pedal to see the movable piece of equipment color blue retreat, and open the main and auxiliary contacts. If we press the brake pedal, the movable piece of equipment returns to its original position, opening the main and auxiliary contacts. The basic internal contact works in this way when energizing the coil this generates an electric field that attracts the movable piece of equipment to the part with electric power, in this way the main and auxiliary contacts close and allow the passage of current to the load. If you sit energizes the coil then the reserve located between the movable piece of equipment and the coil pushes the movable piece of equipment to its place by default. The principle of operation is similar to an electromagnet in a relay. I'll make a test to make all this clear. I'll occupy a socket and as load a light bulb since at the moment I don't have an electric motor. Here I have the cables that will go to the contacts of power to feed the load. I'll lower the switch to make the connections. I'm using thin cables since our load is a low-power light bulb that I'm only going to use as a
