CDM3-630F/3340 Molded Case Circuit Breaker Product Introduction (English)
The CDM3-630F/3340 molded case circuit breaker is a circuit protection device specifically designed for low-voltage power distribution systems. Operating in 230V AC environments, it provides reliable overcurrent and short-circuit protection for industrial and commercial power distribution cabinets, equipment control panels, and related applications.
Constructed with high-strength engineering plastics, the housing delivers excellent insulation and mechanical durability. The multi-layer arc suppression system effectively controls arc propagation, ensuring swift and reliable circuit interruption. Precision bimetal tripping mechanism combined with optimized contact materials enables accurate delayed protection during overload conditions, balancing operational stability with circuit safety.
Pre-installed with 80cm flexible insulated leads for convenient field installation, the product features anti-loosening terminals compatible with 6-50mm² conductors. Three-pole linked operation guarantees simultaneous phase interruption, preventing system imbalance caused by single-phase faults. The transparent protective cover allows visual inspection of contact status, facilitating routine maintenance.
Maintaining consistent performance in humid, dusty, or temperature-fluctuating environments, its compact design enables efficient space utilization in standard DIN rail installations. The product undergoes rigorous factory testing procedures to ensure reliable electrical isolation, suitable for motor protection and main circuit branch protection. Optimized structural design enhances heat dissipation efficiency while maintaining a 150mm×90mm×75mm footprint, making it an ideal solution for modern power distribution system upgrades.
