CDM3-400H/42002B 350A Molded Case Circuit Breaker
The CDM3-400H/42002B 350A molded case circuit breaker is an intelligent protection device engineered for modern power systems. Utilizing modular structural design and engineering plastic encapsulation technology, it is specifically designed for electrical energy distribution and circuit protection in 50/60Hz AC networks. The triple-stage protection mechanism integrates overload long-time delay, short-circuit short-time delay, and instantaneous tripping functions, effectively enhancing operational continuity of power distribution systems.
Equipped with a high-sensitivity electromagnetic release mechanism, the product demonstrates exceptional breaking capacity and precise response characteristics, achieving fault isolation within milliseconds. The contact system combines silver-based alloy materials with arc chute design, effectively reducing arc energy and extending electrical durability. The 350A frame configuration supports both cable direct connection and busbar installation, accommodating various switchboard layouts.
With compact structural design featuring industry-leading width optimization, the breaker allows vertical or horizontal parallel installation, saving over 35% cabinet space. The ergonomic handle mechanism provides clear "ON-OFF-TRIPPED" status indication, supporting both manual operation and optional motorized control. The enclosure employs eco-friendly reinforced engineering plastics with outstanding high-temperature resistance and impact strength, suitable for operation in challenging environments ranging from -25℃ to +70℃.
Ideal for low-voltage distribution systems in industrial plants, commercial buildings and rail transit applications, it delivers reliable protection for motors, transformers and electrical equipment. Optimized thermal stability design and mechanical interlock structure ensure consistent protection performance even under frequent start-stop conditions. Maintenance-friendly features throughout product lifecycle enable rapid component replacement and status monitoring capabilities.
