If you’re looking for information on wiring a Square D 8536 motor starter, you’ve come to the right place. This article will provide a comprehensive guide on how to wire the starter, including step-by-step instructions, diagrams, and FAQs to help you get the job done quickly and efficiently.
Section 1: Understanding the Square D 8536 Motor Starter
The Square D 8536 motor starter is an electromechanical device that is used to start and stop motors. It consists of a contactor, overload relay, and control circuits. The contactor is responsible for switching the power to the motor on or off, while the overload relay protects the motor from damage caused by overloads and short circuits.
The control circuits of the starter include a control transformer, start and stop pushbuttons, and a set of auxiliary contacts that can be used to control other devices in the circuit.
Before you begin wiring the Square D 8536 motor starter, it’s important to understand the function and operation of each component in the starter.
Contactors
Contactors are electromechanical switches that are used to control electrical power circuits. In the Square D 8536 motor starter, the contactor is responsible for switching the power to the motor on and off.
When the start pushbutton is pressed, the control circuit sends a signal to the contactor, which closes its contacts and allows power to flow to the motor. When the stop pushbutton is pressed, the control circuit sends a signal to the contactor, which opens its contacts and cuts off power to the motor.
Overload Relays
Overload relays are designed to protect motors from damage caused by overloads and short circuits. In the Square D 8536 motor starter, the overload relay is connected in series with the motor and monitors the current flowing through the circuit.
If the current exceeds a certain threshold, the overload relay will trip and open its contacts, cutting off power to the motor and protecting it from damage.
Control Circuits
The control circuits of the Square D 8536 motor starter are responsible for controlling the operation of the starter. The control circuits include a control transformer, start and stop pushbuttons, and a set of auxiliary contacts that can be used to control other devices in the circuit.
The control transformer steps down the voltage of the power supply to a lower voltage that is suitable for the control circuit. The start and stop pushbuttons are used to start and stop the motor, while the auxiliary contacts can be used to control other devices in the circuit, such as lights or alarms.
Section 2: Wiring the Square D 8536 Motor Starter
Wiring the Square D 8536 motor starter is a relatively simple process, but it’s important to follow the correct wiring diagram to ensure that the starter functions properly and safely.
Step 1: Mounting the Starter
The first step in wiring the Square D 8536 motor starter is to mount it in a suitable location. The starter should be mounted on a flat and level surface that is free from vibrations and other sources of mechanical stress.
Once the starter is mounted, you can begin wiring it according to the wiring diagram provided by Square D.
Step 2: Wiring the Control Circuit
The control circuit of the Square D 8536 motor starter consists of a control transformer, start and stop pushbuttons, and a set of auxiliary contacts that can be used to control other devices in the circuit.
To wire the control circuit, follow these steps:
- Connect the control transformer to the power supply using appropriately sized wires.
- Connect the start and stop pushbuttons to the control circuit.
- Connect the auxiliary contacts to the devices that they will control.
Be sure to follow the wiring diagram provided by Square D to ensure that the control circuit is wired correctly.
Step 3: Wiring the Power Circuit
The power circuit of the Square D 8536 motor starter consists of the contactor and overload relay, which are responsible for switching the power to the motor on and off and protecting it from damage caused by overloads and short circuits.
To wire the power circuit, follow these steps:
- Connect the power supply to the L1, L2, and L3 terminals on the starter.
- Connect the motor to the T1, T2, and T3 terminals on the starter.
- Connect the overload relay to the power circuit according to the wiring diagram provided by Square D.
Be sure to follow the wiring diagram provided by Square D to ensure that the power circuit is wired correctly and that the motor is protected from damage.
