Understanding 3 Phase Power
To understand 3 phase power, you first need to know what 3 phase means. Basically, it's a method for distributing alternating current electric power. Instead of providing power through a single phase, it uses three phases.
Each phase is 1/3 of a cycle out of phase with the other two. This results in a more constant power supply with less fluctuation. 3 phase power is commonly used for large loads like industrial equipment, pumps, HVAC units, and electric vehicles.
The three phases are provided through three separate conductors. Each conductor carries one phase of power to the load. The phases are labeled A, B, and C. For most 3 phase power, phases A and C are 120 degrees out of phase, and B is 240 degrees out of phase from A.
A 3 phase contactor is used to control this 3 phase power and send it to electrical loads and equipment. It contains three electromagnets, one for each phase, that are individually energized to close or open each phase circuit.
When wiring a 3 phase contactor, you'll connect each of the three power supply phases to one side of the contactor. The load phases are then connected to the other side. So phase A from the supply connects to phase A on the load side, and so on. The contactor will then open or close all three phases at once when its coil is energized.
Make sure to check a reference for the specific voltages in your country and region. In the U.S., 3 phase power is typically 208V for smaller loads or 480V for larger industrial uses. Properly wiring a 3 phase contactor and understanding 3 phase power principles will ensure safe and reliable operation of your equipment and motors.
Wiring the 3 Phase Contactor
3 phase motor and contactor wiring is not as complicated as it looks. With a basic understanding of components and proper connections, you can easily hook up your motor. Focus on one phase at a time and follow the step-by-step process in this article, complete with an easy-to-understand video animation. With practice, you'll become an expert in high voltage connections.
Connecting the Power Supply
First, connect the power supply leads to the appropriate terminals on the contactor. The three power supply phases (typically red, yellow and blue wires) should attach to terminals marked 1T1, 3T2 and 5T3. Secure the wires in place with wire nuts or by tightening the contactor’s built-in clamp screws.
