What is connected to the T1, T2, and T3 terminals on a contactor?

The T1, T2, and T3 terminals on a contactor are specifically designed for load connections. These terminals facilitate the connection of load wires which carry the current to the equipment being controlled by the contactor. When the contactor is energized, it closes the circuit at these terminals, allowing electrical power to flow to the load, which can be anything from a motor to lighting.

Understanding that these terminals deal directly with the load is essential for anyone working with contactors, as it helps in the safe and effective integration of electrical components in a circuit. The load wires are critical in determining the capabilities and ratings of the contactor, ensuring that it can handle the intended electrical load without overheating or failing.
