CDM6S-800M/4300A 400A Molded Case Circuit Protection Device Technical Description
The CDM6S-800M/4300A 400A molded case circuit protection device is an intelligent electrical protection solution developed for modern power distribution systems. Featuring modular construction design, it provides reliable circuit protection and control functions in 380V/415V AC distribution networks. The housing is manufactured with high-strength engineering materials using integrated molding technology, incorporating precision electromagnetic mechanisms and thermal-magnetic protection units to ensure excellent mechanical durability and environmental adaptability.
Equipped with an intelligent tripping mechanism, the device enables rapid circuit interruption under short-circuit and overload conditions. The optimized contact system combined with multi-layer arc extinguishing structure enhances breaking capacity while minimizing arc effects. With compact dimensions achieving approximately 15% width reduction compared to conventional products, it accommodates various switchgear installation requirements. The three-position indicator mechanism (OFF/ON/TRIPPED) and clear status observation window facilitate operational maintenance.
Technical specifications include 400A rated operational current and 50kA short-time withstand current, meeting rigorous industrial power distribution demands. Specially designed terminals ensure secure connection for 35-185mm² conductors, with copper-aluminum composite materials reducing contact resistance. Integrated temperature compensation mechanism automatically adjusts protection accuracy across -25℃ to +70℃ operating range, maintaining stable performance parameters.
Suitable for manufacturing plants, commercial buildings, and infrastructure projects, the device effectively protects cables, transformers, and motor loads. Flexible horizontal/vertical mounting options and maintenance-friendly access points simplify periodic inspections. Standardized accessory interfaces allow expansion with motorized operators and alarm contacts, supporting intelligent power system upgrades. Corrosion-resistant surface treatment and vibration-damping structural design enhance long-term operational reliability in diverse industrial environments.
