TIBCON Capacitor Duty Contactor is specially designed for Capacitor switching applications. Since the capacitor switching incorporates high in-rush in power, the contactors are provided with damping resistors that limit the value of in-rush power to a safer value. These Contactors are fitted with Front-mounted Block of three early make Auxiliary Contacts that are in series. These are equipped with quick discharge damping of 6 Resistors that are assembled 2 per phase so as to limit peak current at value within Contactor. This makes the capacity to a normal rating. Capacitor current is carried by main contacts that after closing will effectively short out the resistors.
