The small AC contactor model CJX2-K12 is a commonly used electrical device in power systems. Its contact function is reliable, its size is small, and it is suitable for the control and protection of AC circuits.
CJX2-K12 small AC contactor adopts a reliable electromagnetic mechanism to realize switching control of the circuit. It usually consists of electromagnetic system, contact system and auxiliary contact system. The electromagnetic system generates electromagnetic force by controlling the current in the coil to attract or disconnect the main contacts of the contactor. The contact system consists of main contacts and auxiliary contacts, which are mainly responsible for carrying current and switching circuits. Auxiliary contacts can be used to control auxiliary circuits such as indicator lights or sirens.
