A contactor is a switching device, widely used for the switching of motors, capacitors (for power factor correction), and lights. As the name indicates it is used to make or break contacts like an ordinary on-off switch. The only difference is that the contactors have an electromagnet that holds the contacts when energized whereas switches do not have it.
Capacitor switching application leads to very high current peak at capacitor energization. UA..RA contactors are designed with damping resistor to handle current peaks without limitation.
Capacitor contactors with damping resistors have become almost a must in PFC-applications. EPCOS is offering a broad range of well-approved contactor series, covering a range Fault level of supply network Ohmic resistance of capacitor itself, distribution switch gear and connection cables or conductors Fig 2:

Here are a few reasons why using an AC contactor for DC supply is not advisable: Arcing and Contact Wear: DC circuits tend to produce more arcing when contacts open or close compared to AC circuits. This arcing can lead to increased wear and tear on the contactor, potentially reducing its lifespan and reliability. Capacitor Contactor: A
Hence, capacitor duty contactors are best suited for capacitors switching applications which not only save cost but also improves the life of the equipment. Technical Data

A contactor is an electrically controlled electromechanical switch, similar to a relay, whose function is to break or make the electrical connection between a connected load and the main power supply. Contactors are used to switch currents ON and OFF in circuits, where the switched current is at a much higher level than the supply current.
After the contactor is completely closed, the auxiliary contact is disconnected, the series resistance is cut off and the contactor''s main contact supplies power to the capacitor. The function of the capacitor contactor is to reduce the starting
If your 12 volt supply comes on with the same contactor closure,you can use that to drive the time delay relay,but if it is already on,you need to switch it with the contactor. My suggestion in that case, is to ignore the existing 12v supply,& connect a small transformer with its primary switched by the contactor,then connect the time delay
The Capacitor and Contactor are a Team The capacitor and contactor work together in your air conditioner or heat pump to help power the fan and compressor.

As soon as my switch is closed, the capacitor will provide the full energy required to close the contactor coil. From that point on, the 24V source will provide enough energy to hold the contactor in, while also slowly charging the capacitor. Once the switch is re-opened, the diode with suppress the back EMF, while the capacitor recharges.
