The CDM6S-400L/3320 molded case circuit protection device is a high-performance solution designed for industrial and building power distribution systems. With 400A rated current capacity and innovative plug-in rear-terminal connection design, it delivers reliable overload and short-circuit protection for electrical distribution networks.
Featuring modular architecture, the product integrates compact structural layout with high-density components. The monoblock housing manufactured from reinforced engineering plastics encapsulates precision electromagnetic trip mechanism and bimetal thermal protection system, enabling automatic detection of circuit anomalies and rapid disconnection. The plug-in terminal system supports rear-mounted installation, optimizing wiring compartment space for enhanced cable management efficiency while simplifying cabinet internal layout.
Equipped with triple-stage arc extinguishing chambers, the device adopts longitudinal metallic splitter plate technology to improve arc quenching performance. Silver-alloy contacts combined with double-breakpoint configuration ensure low contact resistance and extended electrical durability. The spring-operated mechanism with position indicator allows manual operation and status verification.
Applicable to AC distribution systems, this product is widely deployed in factory power cabinets, commercial building main switchrooms, and data center power units. The rear-terminal connection facilitates front-access maintenance, particularly suitable for space-constrained compact distribution solutions. Reinforced isolation barriers and insulated partitions provide operational safety for maintenance personnel.
Through optimized thermal conduction paths in current-carrying components, the device maintains stable temperature rise during continuous full-load operation. Intelligent time-delay protection prevents nuisance tripping from temporary overloads while ensuring accurate fault current discrimination. Versatile accessory options including auxiliary contacts and shunt releases allow flexible system expansion according to application requirements.
