CJ19 Change Over Capacity AC Contactor

Short Description:

CJ19 Changeover capacitor contactor is especailly used for low voltage shunt capacitor. And it widely used in reactive power compensation equipment with AC 50Hz and voltage 380V, inrush current system in the contactor can decrease shock to capactior and lower switching overvoltagein while breaking a circuit. Moreover, it can replace transfer device which are composed of one contactor and three current limiting reactors, its feature is small, light, joins convenient and reliable, huge capacity of turning on/off.
This product conforms to GB14048.4,IEC60947-4-1 standard.

Outline And Mounting Dimension

CJ19-25~43

CJ19-63~95

Design Feature

The contactor is a direct moving double breakpoint structure, the contact system is divided into two layers, and the upper layer
has three pairs of current limiting contacts and current-limiting resistance consist of inrush current device. When it is closed, it is
connected to the work contact after several milliseconds, and the permanent magnetic block in the current limit contact is released
by the spring reaction. Disconnect the current-limiting resistor to make the capacitor work properly and the contactor internal circuit
connection diagram (see figure 3).
CJ19-25~43 have two auxiliary contacts, CJ19-63~95 have three auxiliary contacts.
For CJ19-25~43, Screws are available for installation, as well as the 35mm standard din rail.
For CJ19-63~95, 35mm or 75mm standard din rail can be mounted are available for installation.
