英文版：
CDM6I-400S/3300 400A Molded Case Circuit Breaker is a protective device developed for low-voltage distribution systems, suitable for AC 50Hz networks with rated operational voltage up to 690V. Featuring modular construction, its core components include precision electromagnetic trip mechanism and thermal bimetal overload protection system, enabling rapid response to line faults such as overload and short circuit.
The enclosure adopts high-strength engineering plastic formed by integral molding process, demonstrating excellent insulation performance and mechanical durability. The arc extinguishing chamber incorporates multi-layer metal grid design, effectively reducing arc duration and enhancing breaking reliability. With rated current up to 400A and breaking capacity of 3300A, this product meets the requirements of general industrial power distribution scenarios. The three-position indicator (ON/OFF/TRIP) provides intuitive status monitoring.
Supporting both horizontal and vertical installation, the busbar connection terminals feature silver-plated treatment to minimize contact resistance. Modular accessory design allows integration of auxiliary contacts and shunt trip units. Suitable for main circuit protection in building power distribution, mechanical equipment, and renewable energy systems, it provides fundamental safeguards for electrical network stability.
Safety considerations are emphasized through fully enclosed structure and isolation barrier design, preventing foreign object intrusion. The ergonomic handle with safety lock hole ensures operational security. Optimized internal component layout achieves compact dimensions while maintaining balanced heat dissipation across functional units.
