Cj19 3phase Capacitor Changeover AC Magenetic Power Contactor

Application of AC contactor

CJ16/19 is developed by our company on the base of 3TK44 capacitor contactor of Siemens company Germany.

It's structure is compact, main circuit composed with resistance on -off switch joint the main circuit is convenience,

 is nidely used as a contactor in controlling small electric capacitor, the model meaning as right .

    The contact system of contactor is three-phase main circuit, composed by eight pieces contact block from upside and daminside. There is one contact block was switch on in advance in each main circuit, switch-overressistor only two,

the cpacitor group is jointed as triangle, so when resistor switch over circuit was sitchon, every capacitor circuit will  connected with resistor.

    The contacor have two pieces of auxilliary contact block, the function is 2NO, 2NC or 1NO+1NC, this is chosed by user.

    The mounting of this contactor is very convenience, you can use two pieces of M4 screw make it stable, or can use 35mm Din real mou
