Contactors and Protection Relays
A contactor is a special type of relay used for switching an electrical circuit on or off. Contactors and relays function in very similar way, with the main difference being the loads they are designed to handle. Contactors are used in applications with higher current carrying capacity, typically built for and used in 3-phase applications. Contactors are most commonly used with electric motors and lighting applications. Relays are used for lower current or low voltage switching, more commonly used in single-phase applications. A contactor joins 2 poles together, without a common circuit between them. A relay has a common contact that connects to a neutral position. As the largest selling line of contactors in the world, our TeSys product line provides high reliability with long mechanical and electric life. Select from a complete line of accessories for motor and load control. TeSys contactors and relays are available for both NEMA and IEC applications, and are certified by major standards around the world.
IEC style contactors are more application-specific, meaning they’re rated to specific motors and purposes. With IEC contactors, the focus is on performance for the expected life of the equipment under control. And given it’s more modular and component-based, it’s a simple matter to replace any failed component – they typically just snap into a DIN rail-type mounting system in the smaller sizes. IEC in an international standard. You’ll find IEC devices all over Europe and elsewhere in the world.
