CHAC Unveils the CQM6 Series MCCB: Pioneering Innovation in Compact Circuit Protection
At Zhejiang Chuangqi Electric Co., Ltd. (CHAC), leveraging over 30 years of expertise in low-voltage electrical solutions, we are proud to launch the CQM6 Series Molded Case Circuit Breaker (MCCB). Engineered for superior overload and short-circuit protection in power distribution and motor control systems, this series sets a benchmark in compact design and modular versatility. With frame-rated currents from 125A to 1250A and breaking capacities up to 75kA (Icu/Ics at 400/415V), the CQM6 integrates advanced thermal-magnetic trip units for precise fault detection, alongside insulation voltages of 800V and impulse withstand of 8kV. Its miniaturized footprint facilitates seamless integration into space-constrained panels, while supporting extensive accessories—including shunt releases, undervoltage releases, auxiliary switches, and motorized operations—for tailored system customization. The CQM6 addresses the evolving needs of smart grids, industrial automation, and energy-efficient infrastructures, empowering engineers to achieve enhanced selectivity, reduced installation complexity, and optimized operational resilience in challenging electrical environments.
Key Innovative Features and Specifications:
The CQM6 Series innovates by offering versatile N-pole protections (A/B/C/D types) and decoupler methods, facilitating future-proof designs for emerging tech like EV charging or renewable systems, ultimately lowering total ownership costs through efficiency gains. In application scenarios, it excels in smart factories for automated motor control with remote shunt releases, or in solar farms for reliable distribution protection under variable loads.
