【English Version】
CDM6I-400M/4200B 400A Molded Case Circuit Breaker is a high-performance protection device specifically engineered for low-voltage power distribution systems. Featuring a modular structure design, this product offers a rated current of 400A with maximum breaking capacity up to 42kA, suitable for AC 50/60Hz power networks with rated operational voltage up to 690V. The composite housing combines high-strength engineering plastics with metal components, delivering both mechanical durability and reliable insulation performance.
The product excels in intelligent protection capabilities and consistent operational reliability. Its precision-engineered electromagnetic trip mechanism enables dual protection functions: overload time-delay protection and instantaneous short-circuit protection. The contact system utilizes special alloy materials combined with an optimized arc chute structure, effectively suppressing arc propagation to ensure safe interruption. Operational mechanism has undergone 20,000-cycle endurance testing, maintaining stable contact pressure and consistent switching speed.
Supporting multiple installation methods, the device is compatible with standard rails or fixed-mount applications. The compact design achieves high space efficiency with single-pole width of only 72mm. Transparent cover integrates visible switching status indicators for quick operational monitoring. Plug-in terminal design simplifies wiring procedures, accommodating conductors from 25mm² to 400mm².
Ideal for main circuit protection in industrial plants, commercial buildings, and infrastructure projects, it effectively prevents electrical hazards caused by overloads and short circuits. Optimized thermal management ensures housing surface temperature rise remains below 55K during full-load operation, guaranteeing long-term stability. With IP40 protection rating, the device reliably operates in standard industrial environments.
