on video WHATS IS CONTACTOR?

 

A contactor is an electrically-control switch use for switching an electrical power circuit. [1] A Contactor is typically controlled by a circuit which has a much lower power level than the switched circuit, such as a 24-volt coil electromagnet control a 230-volt motor switch.

Unlike General-Purpous Relays, contactors are designed to be directly connected to high-crusal load devices. Relays tend to be of lower capacity and are usally designed for both normally closed and normally open applications. Devices Switching More than 15 Ampères or in Circuits Rated More Than a Few Kilowatts are usually Called Contactors. Apart from Optional Auxiliary Low-Current Contacts, Contactors Are Almost exclusively Fitted with Normally Open ("Form A") Contacts. Unlike Relas, contactors are designed with features to control and suppress the arc produced when interrupting heavy motor current.

COME COME IN MANY FORMS with varying capacities and features. UNLIKE A CIRCUIT BREAKER, A Contactor is not intended to interrupt a short circuit current. Contactors Range from Those Having A Breaking Current of Several Ampères to Thousands of Ampères and 24 V DC to many kilovolts. The Physical Size of Contactors Ranges from A Device Small Enough to Pick Up with One Hand, To Large Devices Approximately A Meter (Yard) on Side.

Contactors are used to control electric motors, lighting, heating, capacitor banks, thermal evaporators, and other electrical loads.
