FAQs About Contactors

Learn more about how electrical contactors support safe, reliable motor control in industrial systems.

A contactor is an electrically controlled switch used to control high-power loads, such as motors, lighting systems, and heating equipment. It allows a low-power control circuit to safely operate heavy-duty electrical loads.

While both devices switch electrical circuits, a contactor is designed for high-power applications, such as motors and industrial equipment. A relay typically controls lower voltage or current applications, like electronic circuits or small machinery.

When choosing a contactor, you should consider:

  • Motor horsepower and full load current
  • Voltage rating (AC or DC)
  • Application type (inductive loads like motors vs. resistive loads like heating)
  • Environmental factors (indoor/outdoor use, humidity, dust) Wistex can assist with matching the right contactor to your specifications.
