6 FAQs about [Principle of capacitor contactor]

What is a capacitor switching contactor?

In capacitor banks, capacitor switching contactors are used to switch capacitors based on the reactive power requirements. They are specially designed to control high transient currents formed during switching. Additional resistors are provided to reduce inrush currents while switching.

What is a capacitor duty contactor?

The new range of capacitor duty contactor has been launched to provide a reliable and economical solution for capacitor switching applications. In Low Voltage industrial installations, capacitors are mainly used for reactive power correction (raising the power factor).

What is the main function of a capacitor contactor?

The main function of the capacitor contactor lies in the auxiliary contact, which is very different from the conventional contact. The 33 and 34 contacts on the auxiliary contacts of the capacitor contactor have the same function as the conventional auxiliary contacts, which act together with the main contacts of the contactor.
