The primary means of controlling electrical circuits remain the same while technology has improved over years. This article examines how they work and the different types of electric contactor among these are contactors. It also looks at the differences between DC contactor and AC contactor as well as relay and contactor.

Contactor

Making or breaking the connection between the load and the power supply is the main role of a contactor is an electromechanical switch. At a much lower level, the contactor is usually powered and electrically controlled than the switched circuit. For example, controlling a 230-volt motor switch, you would have a 24-volt coil electromagnet.

Including controlling other electrical loads, thermal evaporators, electric motors, capacitor banks, lighting and heating, a contactor’s applications are useful. In capacity and size, Contactors range. Measuring about a meter on the side, you have those that you can easily lift with your hand to massive ones. Ranging from a few amperes to those from 24V DC to many kilo volts and thousands of amperes, you also have those with a breaking current.
