二、English Version
The CDM3-400H/42002A 225A molded case circuit breaker is a multi-functional protection device specifically engineered for modern power distribution systems. It operates effectively in AC 50Hz networks with rated voltages up to 400V, providing reliable safeguards against overload and short-circuit faults for electrical circuits and connected equipment.
This product demonstrates three key technical strengths: The intelligent trip mechanism ensures rapid response to abnormal current fluctuations with minimized operational time deviation. Its double-break contact structure combined with an optimized arc extinguishing system significantly enhances arc-breaking efficiency while reducing thermal impact. The compact design achieves approximately 15% size reduction compared to conventional models, facilitating flexible installation in switchgear cabinets. The housing utilizes high-performance engineering plastics with excellent heat resistance and impact strength, maintaining stable performance across a broad temperature range from -25℃ to +70℃.
The operating mechanism has undergone rigorous testing with over 100,000 mechanical cycles, verifying its dependable switching durability. Multiple control options are available including manual handle operation and motor-driven actuation, with expandability for auxiliary contacts and alarm signals. Typical applications encompass main power distribution in commercial complexes, motor control centers for industrial production lines, and circuit protection in photovoltaic combiner boxes, effectively enhancing the safety and operational reliability of power supply systems.
