How a contactor works

Medium voltage contactor , because there are some coil like closing coil, open coil, holding coil, how those things work sir(the principle)? How contactors work presented by Katie Rydzewski for Galco TV. We can have complete inside view of contactor.

The components of contactors are seen i. Cool stuff am happy with this one.

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.

A contactor has three components.

This includes power contacts, auxiliary contacts, and contact springs. The electromagnet (or coil) provides the driving force to close the contacts. They usually handle very heavy loads like an electric motor, lighting and heating equipments and so on.

According to the loads they handle, they vary in sizes . Contactors are electrically controlled switching devices used for switching of e. This video explains the principle of operation of contactors. Chris covers the basics of how electrical relays and contactors work. We teach you the basics of how they work and what they are used for.

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. The SC-E contactors work with either the conventional adjustable overloads or the Manual . Relays and contactors both are electromagnetically operated switch. An easy-to-understand explanation of how relays use electromagnets to switch electrical circuits on and off.

The electrical wiring needed to wire these is very simple once you have been shown how to do it.

Electricians that take pride in their work will run the wire as shown in the video and follow the national electrical code. How HVAC Contactor Relays Work , Troubleshooting Procedure, 24v, 120v, 240v Wiring, Problems signs that they are Ba Reading coil resistance, fla ratings, an. Information on how relays work , including relay diagrams and different relay types.

The switch provides the desired function, to turn current flow on and off. Reed relays consists of two reeds. It should be noted that though they are similar in design, magnetic contactors are not circuit breakers.
