Product catalog summary
Application and Features: The CJ19(16) series switching capacitor contactors are designed for switching low voltage parallel capacitors. They are used in reactive power compensated equipment with AC 50Hz and voltage up to 380V. These contactors include a device to restrain surge current, reducing the impact on capacitors during switching and minimizing overvoltage during breaking. They are compact, lightweight, and easy to install, replacing traditional switch-over devices.
Service Conditions: The contactors are suitable for altitudes up to 2000m, with ambient temperatures ranging from -25℃ to +40℃. They can operate in environments with relative humidity not exceeding 90% at +25℃, and must be free from corrosive gases, conductive dust, and flammable or explosive media. The installation surface should not incline more than 5 degrees, with a pollution level of 3 and installation category III.
Main Technical Parameters: The contactors control capacitors with capacities ranging from 6 to 32 kvar at 230V and 12 to 50 kvar at 400V. They have a rated insulation voltage of 500V and a working voltage of 380V. The conventional thermal current ranges from 25A to 95A, with an AC-6b rated working current from 17A to 72A. The control coil voltage options are 220V or 380V, with an insulation level of B. The auxiliary contact has a conventional thermal current of 6A or 10A, with an operating frequency of 120 times per hour, an electric life of 105 cycles, and a mechanical life of 106 cycles.
Outline and Installation Size: The CJ19(16)-63.85.95A and CJ19(16)-25.32.43A models have specific outline and installation sizes. They can be installed using screws or a standard rail fast belt embedded mode, with rail widths of 35mm or 75mm depending on the model.
Application and Maintenance: Ensure firm connection of inlet and outlet wires to prevent arcing. If surge current exceeds the contactor's capacity, replace the resistor. Discharge equipment should have an insulation voltage more than twice the operating voltage to prevent damage. When ordering, specify the model, specification, and coil voltage clearly.
Order Information: For ordering, provide the model, specification, and coil voltage, e.g., CJ19-32/11, coil voltage 380V, 24 pieces.
