Electrical Auxiliary Contact Symbol

Since i am using more than 1 of the auxiliary contact blocks on the same relay i do not know how to handle the pin list.

Electrical auxiliary contact symbol. The contacts are the current carrying part of the contactor. Available in svg png jpg dxf dwg formats. Although control symbols vary throughout the world the symbols used in this course are common in the united states and many other countries. Relay symbols and electromagnets.

The electromagnet or coil provides the driving force to close the contacts the enclosure is a frame housing the contacts and the electromagnet. Auxilliary contacts symbols for use in electrical pneumatic and hydraulic schematic diagrams. I use the multi catalog button to add the contacts to the coil symbol. A contactor has three components.

Contactors symbols for use in electrical pneumatic and hydraulic schematic diagrams. No contacts relays contactors and magnetic motor starters normally have more than one set of auxiliary contacts. Integral 32 and 63 state of auxiliary contacts 53 54 wiring diagrams 55 57 type s ac combination magnetic starters. Electrical schematics are commonly classified into power circuit and control circuit.

Enclosures are made of insulating materials such as bakelite nylon 6 and. Electrical symbols control circuits can be represented pictorially in various ways. This includes power contacts auxiliary contacts and contact springs. A power circuit consists of the main power device a motor a generator or other power devices along with heavy power conductors contactors.

Reading and understanding electrical drawings electrical drawings can represent anything from a single line power distribution to a power or control circuit and are prepared using various symbols for electrical devices and their interconnections with lines representing conductors or wires used for interconnections. Numerical cross reference systems quickly identify the location and type of contacts controlled by a given device. Electrical circuits electrical circuits are circuits used to interconnect different electrical equipments together to enable the working of an electrical device. Supplementary contact symbols iec symbols static switching control static switching control is a method of switching electrical circuits without the use of contacts primarily by solid state devices.

To read and understand electrical drawings it is necessary to know the. The relay are switching devices activated by signals. One of the more common approaches is to use control logic diagrams which use common symbols to represent control components. These contacts may appear at several different locations in the line diagram.
