Circuit Diagram of Schneider LC1D32BD

Below is a basic wiring diagram for the Schneider LC1D32BD contactor in a motor control circuit:

Components Used:

  1. LC1D32BD Contactor

  2. 3-Phase AC Power Supply (L1, L2, L3)

  3. Motor Load

  4. Push Button Start/Stop Switch

  5. Thermal Overload Relay (Optional for protection)

 L1 ---------+--------------------+--------------------+--------- T1 (Motor)
             |                    |                    |
 L2 ---------+ LC1D32BD Contactor +--------------------+--------- T2 (Motor)
             |  (3-Pole NO)       |                    |
 L3 ---------+--------------------+--------------------+--------- T3 (Motor)

Control Circuit (24V DC):
24V(+) ---- Start Button ---- NO Contact ---- Coil A1
            |                  |
            |                  +-- NC Stop Button --- Coil A2 --- 24V(-)

This configuration allows the motor to start when the Start button is pressed and stop when the Stop button is pressed. The thermal overload relay (if used) provides additional motor protection.
