Contactors are popularly used with electric motors. There are different types of contactors, and the various types have their own sets of features, applications, and capabilities. Contactors can take over a vast range of currents, ranging from a few to thousands of amperes, and voltage from 25VDC to thousands of volts.
These voltages must be electrically isolated from the standard 120 volts AC. Contactors are used to provide this isolation. Contactors use 120 volt standard power to energize a magnetic coil, which causes a set of internal contacts to close and provide higher power to the equipment. Use these tips to learn how to wire a contactor.
Both match a contactor with the job it has to do, but they do so in different ways. The NEMA selection process always results in a choice of a contactor you can use over a broad range of operating conditions. For example, you could use a NEMA Size 5 contactor to run a 50-hp motor operating at 230V or a 200-hp motor at 460V.
Contactors for Capacitor Switching Switching of power factor correction capacitors WEG''s special CWMC contactors line for capacitor switching is designed according to IEC 60947-1 and UL, and provides the best solution for the switching of your power factor correction capacitors. No more in-rush When you switch on a capacitor bank ...
The capacitor switching contactors have resistors connected in series with the capacitors that are switched before the closing of the contacts and are promptly removed post the circuit is energised. Though, this seems a trivial affair, but it plays a pivotal role in significantly damping of inrush current and suppression of voltage transients ...
Understanding Capacitors and Contactors: Essential Air Conditioning Parts. Air conditioning systems are often called refrigerant-based systems because they use the circulation of refrigerant to move heat from inside a building to the outside. But air conditioners don''t actually run off the refrigerant: they''re electrical devices that take ...
The contactor that controls the on and off of the capacitor is called the capacitor switching contactor, which is similar to the conventional contactor. However, there are some differences between them. The contactors for …

An enclosure is used to guard the coil and contactor. Also, it is used to protect the contactors from external physical touch, dust, human contact, etc. The mounting mechanism is just quite an interesting one, it has two screws both are locked in the contactor enclosure. It is used to connect the enclosure, contactor, and arc chute.
– We use a contactor to turn on and off heavy and high voltage electrical devices such as motors, fans, pumps, etc. – The reason that we use a contactor is to control these heavy high voltage electrical devices indirectly and safely via a PLC and not to connect the PLC directly to these output devices.
A contactor is an electrical switch that controls the flow of current in an electrical circuit. It is commonly used in HVAC systems, motor control panels, and other applications that require the efficient operation of electric motors. A contactor wiring diagram typically includes two terminals, labeled A1 and A2.
