The combination of CM6S-400HU and CW3-5000SUA features both high breaking capacity and long lifespan, meeting the needs of the new generation of 400kW+ string inverter solutions.
Products in the energy storage field cover the entire platform from DC1000V to 1500V. The centralized solution CW3MGDC series boasts advantages such as small size and flexible installation; the string-type CM6SDC-630HU has achieved a 40% reduction in size and has been recognized by leading enterprises such as Huawei.

Focusing on the high-voltage demand of wind power AC1800V, we have launched CW3-4000PU circuit breaker, the first CQC-certified AC2000V universal circuit breaker in China. The product size is consistent with the AC1140V product of the same frame, helping users easily upgrade to AC1800V/AC2000V systems without changing the installation structure.

Digital power distribution: CS-Smartlink redefines the operation and maintenance experience
The CS-Smartlink digital system achieves comprehensive monitoring, intelligent early warning, and precise energy consumption management through real-time monitoring of energy efficiency data. The system can be adapted to various distribution room scenarios, ranging from single points to cross-regional ones, providing customized digital solutions for different customers.

Power conversion system: Inductive-free switching ensures continuous power supply
The CST3H series static transfer switch adopts an innovative hybrid design, supplying power through a mechanical switch in the non-transfer state, reducing its own losses by 50% and eliminating harmonic pollution. The optimized voltage detection algorithm achieves a switching time of only 3ms, covering most sensitive load scenarios. The product has passed rigorous EMC testing and is equipped with a color touch screen and a maintenance bypass system, truly achieving plug-and-play and maintenance-free operation.

The CA6 series automatic transfer switch heralds a new era of excitation-type CB-grade products, boasting a minimum transfer action time of ≤0.5 seconds and a mechanical lifespan of up to 10,000 cycles. This product is compatible with the entire CM6 series of circuit breakers and features intelligent functions such as phase angle detection, phase sequence monitoring, and health diagnosis. It supports multiple communication protocols and cloud connectivity. With a rated insulation voltage of 1000V and electromagnetic interference resistance fully meeting Level3 standards, it provides ultimate safety protection for critical loads.

Complete equipment: CGZ1 6.0, smart and secure, flexible and easy to use
The CGZ1 6.0 digital intelligent cabinet integrates CW6 and CM6 circuit breakers with the CS-Smartlink platform, forming a complete digital overall solution. The product boasts a protection level of 4b, and its modular structure significantly simplifies the installation process.

Marine power distribution: professional certification escorts the marine electrical system
The marine power distribution exhibition area showcases a full range of marine application solutions, with rated voltages fully supporting AC690V/DC1500V, fully meeting the high voltage level requirements of modern ships. The products have obtained certification from CCS (China Classification Society), and the accompanying selective analysis software achieves comprehensive protection coordination.
Relying on our unique arc regulation technology, marine circuit breakers achieve high breaking capacity while maintaining a small size, with flexible and diverse wiring methods. The core components are self-developed and self-manufactured, ensuring high reliability of the product. Currently, they have been widely verified in multiple marine projects.
