6 FAQs about Inverter and AC contactor

What is AC contactor?

An AC contactor is an electromechanical switching device designed to switch AC loads on/off. It is used for switching high-current AC loads. The working principle of the AC contactor involves electromagnetic force cooperating with the spring force to make and break the connection between the source and load.

What components make an AC contactor?

The components that make an AC contactor are: Coil – The electromagnetic coil is the heart of the contactor. It creates a magnetic field that pulls the contacts together to close the circuit when energised. This coil is usually made of copper or aluminium wire. It is wound tightly to generate sufficient magnetic force.

What is a high-voltage contactor?

high-voltage contactor, also called a high-voltage relay without distinction in the industry, is widely used in electric vehicles (EV) and hybrid electric vehicles (HEV). It is an electromechanical switching device with a coil to generate a magnetic force that mechanically operates an electric contact.

What are the different types of AC contactors?

AC contactors are mostly available in 3-pole and 4-pole versions. You can choose between them depending on the load type and control circuit requirements. For instance, 3-pole AC contactors are usable in three-phase systems, while 4-pole AC contactors can be used in 3 phase 4 wire system or 1 phase 2 wire system.

Why do you need AC contactors?

AC contactors are necessary control systems to regulate the flow of electricity in heavy electrical loads. That's why they are used in wide applications, ranging from electric motor starters to managing multiple electrical loads in industrial setups. Therefore, consider the above key factors and find the best quality AC contactors for your needs.

Which contactors are suitable for AC motors?

Contactors are suitable for frequently starting and controlling AC motors. ADC3 series contactor conforms to 1EC60947.4 and GB/T 14048.4 standards.
