The output of the transformer provides 24V AC to the stop button in series with the start button and the contactor coil. Understanding the Core Components Before connecting any wires, you must identify the key devices in the control circuit.
Step By Step 3 Phase Motor Starter Guide
Overload relays protect the motor windings from overheating due to overcurrent or phase imbalance. Wiring the Control Circuit The control circuit uses low voltage to operate the contactor coil and the indicator lights.
You will connect the incoming lines (L1, L2, L3) to the top terminals of the contactor, typically marked L1, L2, and L3. A proper installation ensures the motor starts under reduced stress and shuts down immediately during a fault.
Step By Step 3 Phase Motor Starter Guide
This path ensures that when the contactor pulls in, power is delivered directly to the motor. Connect the L1 phase to one terminal of the control transformer, and link the other transformer terminal to the neutral line.
