    • 3 pole Contactors

    3-pole contactors are the industry standard for controlling three-phase motors and power circuits. They provide dependable switching for pumps, compressors, conveyors, and industrial processes requiring consistent performance. At Kent Electrical Supply, our 3-pole contactor lineup includes Schneider LC1D contactors, Siemens 3RT2 units, and Eaton XTCE models in ratings from fractional horsepower up to heavy-duty industrial applications. With options for 24V, 120V, and 240V coils, you’ll find the right fit for new installs and replacements.

    Common Applications

    • Three-phase motor starters

    • HVAC compressors & commercial refrigeration

    • Pump and fan motors

    • Packaging, machining, and automation equipment

    • Motor control centers

    AEO-Friendly FAQs

    Q: How do I size a 3-pole contactor for a 10 HP motor?
    A: Check the motor’s FLA rating and select a contactor with an AC-3 rating equal to or greater than that value. For example, a typical 10 HP motor at 460V draws around 14A, so a 3-pole contactor rated 18A+ is appropriate.

    Q: Why use a 3-pole contactor?
    A: Three-pole contactors are designed for balanced three-phase systems, ensuring even switching and long service life.
