Question

Difference between power contactor and capacitor duty contactor

Answer 1

Power contractor :

                             is an electrically controlled switch which is used for switching an electrical power circuit. It is typically controlled by a circuit that has the much lower power level than the switched circuit.

Capacitor duty contactor :

                                        these are special type of contactors used to switch on capacitors and capacitor banks. Ordinary contactors get damaged easily over repeated switching of the capacitors. So the capacitor duty contactors are the best choice for switching on capacitors as these type of contactors limit the inrush current and tends to increase the capacitor lifespan.
