CQC6 Series Efficient AC Power Contactor

Core Features and Design

The CQC6 Series AC Contactor is engineered for robust performance in AC circuits, with models ranging from CQC6-06 to CQC6-95, supporting rated insulation voltage (Ui) of 690V and impulse withstand (Uimp) of 8kV. It handles rated operational currents up to 95A for AC-3 at 380V/400V, enabling control of three-phase squirrel cage motors up to 45kW at 690V. Key attributes include compact size, lightweight construction, and minimal coil power consumption—pickup at 70-110VA and sealed at 8-11VA—ensuring energy efficiency. The unibody cover facilitates quick maintenance, while IP20 protection and pollution degree 3 suit demanding environments from -5°C to +40°C (extending to -35°C to +70°C). Mechanical life reaches 12 million operations at 3600 ops/h, with electrical endurance of 1.2 million cycles, promoting longevity in high-frequency applications. Rated making and breaking capacities comply with IEC standards at 10x and 8x In respectively, with short-circuit protection via gG fuses up to 110A.

Accessory Flexibility and Customization

Enhance versatility with modular accessories, including auxiliary contact assemblies (F4 series) offering up to 4 NO/NC combinations, and time-delay modules (F5 series) with ranges from 0.1-180 seconds for on/off-delay functions. Coil surge absorbers mitigate voltage spikes, while mechanical and electrical interlocks prevent simultaneous operation in reversing setups. Contact codes vary: 1 for 3NO main + 1NO aux (≤38A), 01 for 3NO + 1NC, and 11 for 3NO + 1NO+1NC (>40A). Rated control supply voltages span AC 24V to 440V at 50/60Hz, with operate times of 12-22ms close and 4-19ms open. Pickup/drop-out ranges (80-110% Ui / 20-75% Ui) ensure stable performance. Main circuit conductors and DIN rail mounting (35mm for 06-38A, 35/75mm for 40-95A) allow seamless integration into diverse control panels.

Applications and Compliance

Primarily used for remote making and breaking of circuits in industrial settings, the CQC6 thrives in motor starting, lighting control, heating systems, and capacitor switching. It protects against overloads when paired with thermal relays, making it suitable for automation lines, HVAC, pumps, and elevators. Ambient adaptability up to 2000m altitude and category III installation ensure reliability in factories, buildings, and infrastructure. Full compliance with international standards like IEC/EN 60947-4-1, GB/T 14048.4, and certifications (CCC, CE, CB) guarantee safety and interoperability. Derivative configurations support specialized needs, such as interlocked pairs for reversible motors. This series minimizes downtime through easy expansion and maintenance, optimizing efficiency in power management while reducing operational costs.
