2021年7月26日 · Learn what a contactor is, how it works, how to wire a contactor, and the difference between a contactor and a relay.
What is a Contactor? Their Operation, Application & Selection
A contactor is a switching device, widely used for the switching of motors, capacitors (for power factor correction), and lights. As the name indicates it is used to make or break contacts like an ordinary on-off switch.
Motor contactors – Construction and Working of Contactors
2023年12月14日 · Contactors are employed for controlling electric motors. In this article, you’ll learn the basic construction and working of contactors. To start up and shut down a three-phase AC induction motor, any three-pole switch with a suitable current rating will suffice.
How contactor controls an electric motor? - EEP
2018年7月2日 · A contactor is a large relay, usually used to switch current to an electric motor or other high-power load. Large electric motors can be protected from overcurrent damage through the use of overload heaters and overload contacts.
Basics Of Motor Starters And Contactors - EEP
2024年11月14日 · Contactors control the electric current to the motor. Their function is to repeatedly establish and interrupt an electrical power circuit. Overload Protection protects motors from drawing too much current and overheating, from literally “burning out.” A contactor can stand on its own as a power control device, or as part of a starter.
Overview of Motor Contactors and AC Drives - Technical Articles
2020年8月18日 · A motor contactor allows current to flow to the motor to turn on and stops the flow of current when it needs to stop running. For more advanced control over a motor, motor drives are often used. Motor drives allow the motor to be run at variable speeds in addition to on and off capabilities.
