CQC1 series High-Duty AC Contactor and Accessories

The CQC1 series AC contactors are designed by CHAC Electric for use in circuits with an AC frequency of 50Hz (or 60Hz), a rated working voltage of 690V, and a rated working current ranging from 9A to 800A. They are primarily used for remotely making and breaking circuits and for the frequent starting and control of AC motors. These contactors can also be combined with thermal overload relays to form electromagnetic starters, providing protection for circuits that may experience overloads. The CQC1 series ensures reliable and efficient operation, making it an ideal choice for industrial applications where precise motor control and circuit protection are essential. It complies with IEC 60947-4, GB/T 14048.4, IEC 60947-5, and GB/T 14048.5 standards.
