CJ19, CJ19B and CJ19C contactors switch low-voltage shunt capacitors in reactive power compensation equipment. The family serves 50Hz, 380V applications and includes capacitor duties up to 60kvar across its wider range. The detailed comparison below gives the specific controlled outputs at 400V.
The inrush-limiting arrangement reduces the current surge when a capacitor step is connected. CJ19C has the corresponding basic ratings of CJ19B and disconnects the resistor branch after its inrush-limiting function is complete. Family size designations include 25, 32, 43, 63, 80 and 95; use the actual capacitor-duty data rather than treating a size designation as the switching current.
Parenthesized values in the CJ19-32 column are the listed CJ16-32 legacy values. CJ16-43 is also identified as a legacy reference for CJ19-43. These references do not replace a check of coil, terminal and mounting requirements.

NO means normally open and NC normally closed. Select the auxiliary block for the required control circuit and verify the terminal marking on the ordered assembly.
The middle drawing identifies the CJ19B/C-32 and -43 construction with a 57mm maximum width, 132mm maximum depth and 125mm maximum height. Additional illustrated bodies show maximum envelopes of 58×104×112mm and 77×151×170mm. Use the matching drawing to check fixing positions, terminal access and the inrush-limiting assembly.
