EASY DOL Starter Wiring Diagram & Connection Explained | Power & Control Circuit for Beginners

Описание: By the end of this video, you will master the connections for every component, including:

⚡️ The Power Circuit: Wiring the 4-pole Main Circuit Breaker (MCB) to the Contactor and Overload Relay.

🚦 The Control Circuit: Connecting the Single-Pole Breaker, Stop (NC) and Start (NO) Push Buttons, and the Contactor Coil (A1 & A2).

🛡️ Motor Protection: Understanding how the Overload Relay protects the motor and how to wire its contacts.

🔄 Latching/Holding Circuit: The crucial connection that keeps the motor running after the start button is released.

💡 Visual Guide: Clear footage and diagrams showing the final connections to the motor terminals.


A. Power Wiring (High Voltage)
Connect the 3 Phase incoming supply to the terminals of the 4-Pole Breaker.

Wire the output of the breaker to the top terminals of the Contactor.

Connect the output of the Contactor to the Overload Relay.

Finally, wire the output of the Overload Relay directly to the 3 Phase Motor terminals. We also show the motor grounding connection for safety.

B. Control Wiring (Low Voltage)
Feed the control voltage (from the Single-Pole Breaker) through the NC (Normally Closed) contact of the Overload Relay (95-96).

Wire the control voltage through the NC Stop Push Button.

Connect the circuit through the NO Start Push Button.

Wire the Contactor Coil (A1 & A2) to energize the main contactor.

THE KEY STEP: Wiring the Latching Circuit using the Contactor's Auxiliary NO contact (13-14) to maintain the coil supply after the Start button is released.
