Contactor - an electrical mechanism switch, adjustable other than manual way, with only one resting position of movable contacts, capable of switching on, switching off, and conducting current under normal circuit conditions, as well as under overloads. Assume I don't know what a contactor is. I read the above definition and…I still don't know.

A contactor is an electrically controlled switch used 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 controlling a 230-volt motor switch.

What is the Electrical Symbol for a Contactor? 3 phase contactor The image above shows a typical symbol for a contactor in an electrical circuit. Different types of contactors can be shown slightly differently but this is the most common type you will see on general electrical drawings. What are the Different Types of Contactors?
Contactor Symbol On Schematic
One-line diagram - a diagram that uses single lines and graphic symbols to indicate the path and components of an electrical circuit. One-line diagrams are used when information about a circuit is required but detail of the actual wire connections and operation of the circuit are not. Line Diagrams Contactors symbols for use in electrical, pneumatic and hydraulic schematic diagrams. Available in SVG, PNG, JPG, DXF & DWG formats 3 Answers Sorted by: 2 Q1 is a 'motor protection circuit breaker' which offers short-circuit, overload and phase failure protection in a single device. The '_F' symbol denotes a knob- or lever-operated 'on/off' device. The 'pulse like' symbol denotes thermal-operated overload/phase failure protection. Figure 3 Symbols for contacts and contactors Both power and control contacts may be either 'normally open' or 'normally closed'. When using the word 'normal' it is meant that the contactor is not energized (i.e. power is not applied to the coil). When the contactor coil is energized, the contacts change their state.

A contactor is an electrical device used for switching an electrical circuit on or off. It is similar to a relay, but the main difference is that the contactor is applied in high current carrying capacity applications and the relay used for low current applications. Generally, these electrical devices feature multiple contacts. A contactor symbol is a representation of a contactor, which is an electrical device used in circuits to control the flow of electricity. A contactor typically consists of a switch and a contact element, with the contact element being the switch's spring-loaded arm or contact point.
How To Read Electrical Circuit Diagram
TDO contact opens at end of timing period. Timing Relay - TDPU indicates timing period starts when coil is energized. TDDO indicates timing period starts when coil is de-energized. O=Operate; R=reset; TC=trip coil; CC=closing coil. (Coils may be seperated on diagram) If shown closed, terminals must be added. A contactor is an electromechanical control device that used to make or break the connection between the load and power supply. The use of a contactor is similar to the relay. But the device used for higher current carrying application is known as a contactor and the device used for lower current applications is known as Relay.
