When it comes to electrical equipment, one of the most important components that you will encounter is a contactor. A contactor is an electromechanical switch that is used to control the flow of electricity in a circuit. It is commonly used in industrial and commercial settings to control motors, lighting, and other electrical devices that require a large amount of power. In this article, we will be discussing the 110 volt single pole contactor wiring diagram.
What is a 110 Volt Single Pole Contactor?
A 110 volt single pole contactor is an electrical switch that is used to control a single-phase electric motor. It is designed to handle up to 110 volts of electrical power and has a single pole that can be used to control the flow of electricity to the motor. The contactor consists of a coil and a set of contacts. When the coil is energized, it creates a magnetic field that pulls the contacts together, allowing electricity to flow through the circuit.
How Does a 110 Volt Single Pole Contactor Work?
A 110 volt single pole contactor works by using an electromagnet to control the flow of electricity in a circuit. The contactor consists of a coil and a set of contacts. When the coil is energized, it creates a magnetic field that pulls the contacts together, allowing electricity to flow through the circuit. When the coil is de-energized, the contacts are released, interrupting the flow of electricity.
The contactor is typically controlled by a low-voltage signal, such as a switch or a control relay. When the signal is received, it energizes the coil, which in turn closes the contacts and allows electricity to flow through the circuit. When the signal is removed, the coil is de-energized, releasing the contacts and interrupting the flow of electricity.
What is a Wiring Diagram?
A wiring diagram is a visual representation of the electrical connections and components in a circuit. It shows how the components are connected and where the wires go. Wiring diagrams are commonly used in electrical engineering and can be useful for troubleshooting and understanding complex circuits.

Here is a wiring diagram for a 110 volt single pole contactor:
| Wire Color | Description |
|---|---|
| Black | Line |
| Red | Load |
| White | Neutral |
| Green | Ground |
To wire a 110 volt single pole contactor, follow these steps:
- Turn off power to the circuit.
- Connect the line wire (black) to the L1 terminal on the contactor.
- Connect the load wire (red) to the T1 terminal on the contactor.
- Connect the neutral wire (white) to the A1 terminal on the contactor.
- Connect the ground wire (green) to the ground screw on the contactor.
- Turn on power to the circuit.
FAQ
What is the purpose of a contactor?
A contactor is used to control the flow of electricity in a circuit. It is commonly used in industrial and commercial settings to control motors, lighting, and other electrical devices that require a large amount of power.
What is the difference between a contactor and a relay?
A contactor is an electromechanical switch that is used for controlling large electrical loads, while a relay is used for controlling smaller electrical loads. Contactors are typically found in industrial and commercial settings, while relays are more commonly used in residential settings.
What is a single-pole contactor?
A single-pole contactor is a type of contactor that has only one set of contacts. It is used to control a single-phase circuit and can handle up to 120 volts of electrical power.
What is the difference between single-phase and three-phase power?
Single-phase power is a type of electrical power that is delivered through a single wire, while three-phase power is delivered through three wires. Three-phase power is commonly used in industrial and commercial settings because it is more efficient and can handle higher power loads.
What is a circuit breaker?
A circuit breaker is an electrical switch that automatically interrupts the flow of electricity when it detects a fault or overload in a circuit. It is designed to protect electrical equipment and prevent damage from electrical fires.
