Switching capacitor contactor CJ19
I. Overview
CJ19-type switching capacitor contactor is the company early reference to Germany's Siemens 3TK44 (capacitor contactor) to improve the design and manufacture of products, its compact structure, the main circuit and the resistance to meet the circuit and one, the main circuit wiring is convenient, Capacitor Capacitor commonly used contactor.
Second, the use of the scope
Conventional traditional compensation applications
Conventional switching method is known as the "static" compensation method, and most of the switch factory currently used in the investment program, the purpose of delay switching is to make the capacitor has enough discharge time to prevent too frequent Of the action on the capacitor and contactor damage, when the controller detects the need for compensation, the controller is delayed for some time (cast delay time can be set), put a group of capacitors, and continue to detect compensation, such as still need Compensation, the controller is delayed for some time, and then put a group of capacitors, until all the investment so far. As the capacitor needs to discharge, can be put into operation again, so the delay time by the capacitor discharge limit can not be set too short, the market generally only use the cycle switch program. Delay switching mode is generally based on the number of switching path number of about 60 seconds to 300 seconds to the reactive power to fill enough, it is suitable for load changes in a smooth situation compensation, if the control system selected nine electrical electrical related products , You can achieve unequal capacitance switching program, the compensation accuracy and switching time will be greatly improved.
Third, the product model
Commonly used model: CJ19-25 11; CJ19-32 11; CJ19-43 11; CJ19-63 21; CJ19-95 21; CJ19-115 21; CJ19-150 21.
Fourth, the main technical parameters
A) Conditions of use: 2000 meters above sea level; Ambient temperature: -25 ℃ ~ 40 ℃ temperature, -25 ℃ when not more than 90%, installation surface gradient of not more than 5 ℃.
B) Rated insulation voltage: 500V
C) control coil operating voltage: 85 ~ 110% of the rated voltage
D) mechanical life of not less than 100 million times
E) electrical life of not less than 200,000 times
F) auxiliary circuit insulation voltage of 500V, rated current 6A, auxiliary contact life of 100,000 times
G) limit the closing surge: I ≤ IC
H) Control coil voltage level: AC 48V, 127V, 220V380V
I) can control the maximum capacity of three-phase power capacitors (see table below)

Fifth, wiring diagram and installation dimensions
Sixth, ordering information
When ordering, please specify the product model, amperage, auxiliary code, voltage, etc., for example: product model CJ19-63 21, voltage 220V, the number of 10.
CJ19 (CJ16) series switching capacitor contactor for AC 50Hz, rated operating voltage to 400V, agreed to heat up to 90A in the circuit, for the connection and breaking the parallel capacitor group to suppress the peak current impact to improve the circuit power factor.
