Contactors are electrical devices used to switch high-power loads in industrial settings. They are responsible for maintaining a steady and safe flow of electricity, but there are a variety of terms associated with them. For example, contactors are often called switches, relays, or electrical contractors. Other synonyms include circuit breakers, solenoids, and magnetic contactors. Additionally, motor starters, magnetic starters, and control devices may all be used to control contactors and their associated circuits. No matter what term is used, it is important to ensure these devices are properly installed and maintained to prevent electrical failures or accidents.
