A simple circuit diagram.
Auxiliary contactor circuit diagram. One contactor may have several auxiliary contacts either normally open or normally closed if required. Check for an auxiliary output contact. Note that one one of the contactor acts as a switch for the start button.
Integral 32 and 63 state of auxiliary contacts 53 54 wiring diagrams 55 57 type s ac combination magnetic starters 58 59 class 8538 and 8539 58 59. And from the mccb breaker i connect the supply to both magnetic contactors. In the diagram i connect the incoming three phase supply l1 l2 l3 to the mccb circuit breaker molded case circuit breaker.
The control circuit economizing auxiliary contacts which are on the improper wiring can kill injure start fires burn out motors or any all of the above. 3ph starter 3ph motor line voltage control three phase 3ph motor starter controlling a three phase motor rev 08 aug the above wiring diagram assumes your magnetic starter has a v coil.

Effectively looking the start button closed. How to wire up an auxiliary contact on a contactor presented by katie nyberg for galco tv. Some contactors provide an auxiliary output contact as a signal to the isolated part of the circuit that the contactor has been energized.
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. L2 wire connected to the both contactors 2nd terminal. All about electrical electronics engineering technology.
This auxiliary contact will not be rated at the higher voltage. These contacts are available in every contactor but these auxiliary contacts in different types just lick normally close and normally open which can set or fit on the contactor motor stater and person can use it for different types of works. Instead it should be rated at 120 volts ac.
The power contacts gains the power for the contactor and the auxiliary contacts is used to bring a loop with the rest of the rest of the devices it is attached to. Either of the two start buttons will close the contactor either of the stop buttons will open the contactor. A simple circuit diagram of contactor with three phase motor.
Here the l1 is connecting to both contactors first terminal. These electromagnets give the initial force to the contacts and make them closed. The contacts are controlled by the electromagnet.
But the reason of this post to learn that what is auxiliary contacts and what is the work of auxiliary contacts on a motor starter.
