Reversing Contactors

Reversing contactors, also known as reversing starters or reverse contactors, are electrical devices used to control the direction of rotation of electric motors. They are commonly employed in various applications where it is necessary to reverse the motor's direction, such as in industrial machinery, conveyor systems, elevators, and more.

The main function of a reversing contactor is to swap the connections of the motor's phases, effectively reversing the polarity and allowing the motor to rotate in the opposite direction. This is achieved by using a combination of power contacts, auxiliary contacts, and mechanical interlocks.

NEMA reversing contactors are contactors that comply with the standards set by the National Electrical Manufacturers Association (NEMA) in the United States for controlling the operation of electric motors in both forward and reverse directions. These contactors are specifically designed to handle the switching and control of motor rotation. NEMA reversing contactors are constructed to withstand the electrical and mechanical stresses associated with motor control. They feature robust construction, durable switching mechanisms, and thermal management to handle the demands of reversing motor operation.
