Contator! Tipos e aplicações de cada um!

Now that you know how a contactor works and how to connect it, we will talk about the application of a contactor and the different types and sizes of this actuating element that is widely used in electric motors. We explain the differences between larger and smaller contactors, and show the possible maintenance that can be performed on more expensive contactors by replacing only the contacts and small parts that wear out. In another video here on the channel, we show the assembly diagram of a contactor actuated using a timer:    • Contator acionado por Timer! Ligação com e...   Now in this video we talk about the specification of a contactor considering the power and other electrical quantities of the circuit, and we teach a little about how to size the contactor. Correctly sizing the contactor in relation to the load it drives is essential to ensure the safety and efficiency of its installation, avoiding overheating and increasing the useful life of the entire system. You will also understand the difference between a relay and a counter, and in another video we talk about the motor circuit breaker, which also acts as a thermal relay:    • Disjuntor motor para acionamento e proteçã...   Electrical installations.
