Unbelievable Electromagnetic Contactor Diagram

An electromagnetic contactor assembly with a sensing circuit for determining contactor state based upon the reluctance of the contactor coil.

Electromagnetic contactor diagram. 2 pole dc contactors description two normally open main contacts for dc circuit positive and negative poles indicated on the front plate eternal magnet installed for the effective arc extinguishing din rail or screw mountable 2no 2nc auxiliary contacts built in as standard ac dc control voltage load load selection type number of dc2 4 ratings continuous auxiliary ac coil dc coil. The coil has an electromagnetic coil and a movable. Therefore the operation of this contactor is safe compared to manual contactor.

Dc operated electromagnetic contactors latched electromagnetic contactors heavy load electromagnetic contactors thermal overload relays electromagnetic contactors electromagnetic switches without enclosure with enclosure non reversible type hs 8 50 frame hs t 8 50 frame shs t 10 50 frame h 65c 800c frame h t 65c 600c frame sh t 65c 600c. 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 controlling a 230 volt motor switch. 48 10 3 dimensions.

A contactor is an electrically controlled switch used for switching an electrical power circuit. An electromagnetic field is generated whenever current flows where the moving coils attract each other. It requires a small amount of control circuit to turn on and off the load.

Unlike general purpose relays contactors are designed to be directly connected to high current load devices. 238000010586 diagrams methods 0 000 description 3 239000003570 air substances 0 000 description 2 mechanically and electrically interlocked electromagnetic contactors. The moving contact is pushed forward by moving core as a result the force created by the electromagnet holds the moving and fixed contacts together.

Study the contactor manufacturer information. The manufacturer information will identify the 2 input pins for 120 volts ac control. These contacts may be indicated on the label as normally open no and normally closed nc.

There are a number of magnetic contactors which are used at every level with different appliances such as. Contactors are available from building and construction supply stores as well as some larger hardware stores. The main categories in which the magnetic contactors are classified are the ac contactors and the dc contactors.
