Function of contactor

Before the advent of solid-state electronics, the camshaft system was commonly . Contactors typically have multiple contacts, and those contacts are usually (but not always) normally-open, so that power to the load is shut off when the coil is de-energized. Perhaps the most common industrial use for contactors is the control of electric motors. The top three contacts switch the respective phases of the . How contactors work presented by Katie Rydzewski for Galco TV.

One of their hallmarks is reliability.

However, like any other device, they are not infallible.

In most cases, the contactor does not simply wear out from normal use. Relays and contactors both are electromagnetically operated switch. There are posts on the working of relays, types of relays and so on.

To know about them click on the links below. Although they have been explained in earlier posts, their wide use and significance needs to be explained in detail.

This allows them to function like any other switch, sometimes changing the state of . Magnetic contactors automatically operate heavy machinery. This video explains the principle of operation of contactors. Medium voltage contactor , because there are some coil like closing coil, open coil, holding coil, how those things work sir(the principle)?

It is an important building block in industrial automation. Contactors are electrically controlled switching devices used for switching of e. A contactor can be operated by electrical, pneumatic or electro-pneumatic means. If the electrical current (amperes) is too high then the contactor opens the circuit to protect the equipment for over-current or for overload. Then its principal function is to work.

The most common use for contactors is the controlling of electric motors.

Contactors have multiple contacts which are normally open, and which causes the load to shut off when the coil . The topic of contactors and relays often raises questions, even amongst professionals. We will address and answer some of these questions in this article . These voltages must be electrically isolated from the standard 1volts AC. Use these tips to learn how to wire a .
