Schneider Contactors
A contactor is a specialized type of electrical relay designed to switch an electrical circuit on or off, especially in applications with high current capacity. While contactors and relays work in a similar way, the main difference lies in the load they can handle. Contactors are built for higher current and are commonly used in 3-phase applications such as electric motors, HVAC systems, and industrial lighting.
Relays, on the other hand, are intended for lower current or low-voltage switching, more often used in single-phase applications. A contactor connects two poles without a common circuit between them, whereas a relay has a common contact connected to a neutral position.
As one of the world’s best-selling contactor ranges, our TeSys contactors deliver exceptional reliability, long mechanical and electrical life, and compatibility with a full range of accessories for motor and load control. TeSys contactors and relays meet both NEMA and IEC standards and are certified by major global regulatory bodies, ensuring performance and safety in demanding environments.
