Square D 3 Phase Motor Starter With Time Clock Wiring Diagrams

A Square D 3 phase motor starter with time clock is a device that is used to control the starting and stopping of a three-phase AC motor. The starter is typically controlled by a pushbutton or switch, and it can be used to start the motor in either the forward or reverse direction. The time clock allows you to schedule the start and stop of the motor, which can be useful for applications such as irrigation systems or lighting.

The following is a wiring diagram for a Square D 3 phase motor starter with time clock:

The following is a description of the wiring diagram:

The L1, L2, and L3 lines from the power source are connected to the L1, L2, and L3 terminals on the starter.
The T1, T2, and T3 lines from the motor are connected to the T1, T2, and T3 terminals on the starter.
The pushbutton or switch is connected to the M and O terminals on the starter.
The time clock is connected to the TC and T terminals on the starter.

To start the motor, press the pushbutton or switch. The starter will energize the M coil, which will close the M contactor. This will connect the L1, L2, and L3 lines from the power source to the T1, T2, and T3 lines on the motor, starting the motor.

To stop the motor, press the pushbutton or switch again. The starter will de-energize the M coil, which will open the M contactor. This will disconnect the L1, L2, and L3 lines from the power source from the T1, T2, and T3 lines on the motor, stopping the motor.

The time clock can be used to schedule the start and stop of the motor. To do this, set the time clock for the desired start and stop times. When the time clock reaches the start time, it will energize the TC coil, which will close the TC contactor. This will connect the L1, L2, and L3 lines from the power source to the T1, T2, and T3 lines on the motor, starting the motor. When the time clock reaches the stop time, it will de-energize the TC coil, which will open the TC contactor. This will disconnect the L1, L2, and L3 lines from the power source from the T1, T2, and T3 lines on the motor, stopping the motor.

Square D 3 phase motor starters with time clocks are available from a variety of online retailers. Prices typically range from \$50 to \$100.
