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. These contacts are physically linked to the main switching mechanism and activate at the same time it does. Enclosures are made of insulating materials such as bakelite nylon 6 and. Hello i have a 5hp 380 volt 3 phase motor that bends reinforcing bars it had 3 contactor s wired to it one energised when power was put on and the other two were for toward and reverse with the overload connected in the bottom its set at 9 amp overload i purchased this motor in auction and all the wires are missing and the contactor s are not working i want to replace all the contactor s.

The electromagnet or coil provides the driving force to close the contacts the enclosure is a frame housing the contacts and the electromagnet. Auxiliary contacts are secondary switching devices that work in conjunction with primary switching equipment such as circuit breakers relays and contactors. Auxilliary contacts symbols for use in electrical pneumatic and hydraulic schematic diagrams. The auxiliary contact is often used in a relay logic circuit or for some other part of the motor control scheme typically switching 120 volt ac power instead of the motor voltage.

I want to be able to put a contactor into the without auxiliaries add auxiliary contacts to the schematic place the contactor symbol on the w d have the wires work right and get the b m to total the contactors and also total the auxiliaries.
