A contactor is a device for creating and breaking an electrical power circuit. For example, we normally use a contactor for turning on & off an electrical motor. Unlike relays, contactor are prepared with qualities to control and suppress the arc made when interrupting heavy motor currents. 

ower capacitors are used to store electric charges & regulate the flow of electricity in an electrical system. Electricity can be unpredictable and can cause fluctuations that can harm other electrical systems in the area.
Industries that use induction motors often have a low power factor in the surrounding distribution line, hence the use of power capacitors. This causes a loss of KVAR and wastes energy. Improving the power factor is considered an important measure for energy conservation.
The device consists of one or more pairs of plates separated by an insulating material (the dielectric) and attached to two terminals that allow the stored energy to be discharged into a circuit when required.
Incorporating capacitors into a power distribution system offers economic and operational benefits, including increasing system load capacity, reducing losses, and improving power factor.
