Technical FAQs 4

What are AC contactors used for?

AC contactors have a crucial role in electrical circuit systems. It helps in the effective control and management of electricity flow across various high-current demanding loads. It is widely used in operating HVAC, compressors, heavy-duty motors, and similar others.

What is a power contactor?

A power contactor is an essential component in electrical systems, providing efficient control over power distribution in industrial, commercial, and even residential applications. By understanding the power contactor working principle, types, and specifications, you can select the right contactor for your needs.

What is an inverter in power electronics?

An inverter in power electronics is a device that converts direct current (DC) into alternating current (AC). It plays a vital role in systems where AC power is needed but only DC is available, such as in solar power systems, batteries, and electric vehicles. The inverter makes it possible to run AC-powered appliances using DC sources.

How does an AC contactor work?

The operation of an AC contactor is based on electromagnetic principles. When an electric current passes through the coil, it generates a magnetic field that attracts the armature, causing the contacts to close and complete the circuit.
