What is an AC contactor?
An AC contactor is an electrically operated switching device used to control motors and other loads. Energizing its coil changes the state of the main contacts, allowing frequent remote control within the device operating characteristics.
A contactor is not selected by frame size alone and does not replace short-circuit or overload protection. Load type, utilization category, operational current, coil supply, switching frequency, auxiliary contacts and protective-device coordination must be checked.

How to choose an AC contactor
Start with the load duty and coil supply, then coordinate protection and accessories.
Utilization category and load
Match motor, heating or other switching duty to the published device rating.
Operational current and voltage
Use the rating stated for the applicable utilization category and system voltage.
Coil voltage and frequency
Confirm the control supply and coil designation on the exact product.
보조 접점 및 액세서리
Define interlocking, signaling and overload-relay requirements before ordering.
Coordinate the motor starter
The contactor, overload relay and short-circuit protective device perform different functions and must be coordinated.

AC Contactor Selection Questions
상세 회로 검증 전 제품군 비교를 위한 빠른 답변.
What is an AC contactor used for?
An AC contactor provides electrically controlled switching for motors and other loads within its published utilization ratings.
How should an AC contactor be sized for a motor?
Use the motor data, system voltage, utilization category, operational current, duty and coordination requirements rather than relying on motor power alone.
Does a contactor protect a motor from overload?
A standard contactor performs switching. Motor overload and short-circuit protection require coordinated protective devices.
Why does coil voltage matter?
The coil must match the available control voltage and frequency. An incorrect coil supply can prevent reliable operation or damage the device.
Can auxiliary contacts be added?
Accessory availability and contact arrangements vary by series. Confirm the required auxiliary functions before selecting the model.
