The CDM6S-800M/4300B Molded Case Circuit Protection Device is a fixed-mount electrical solution specifically engineered for power distribution systems. Featuring rear-mounted wiring configuration and 400A current rating, this product delivers reliable circuit protection for industrial power networks, commercial buildings, and public infrastructure applications.
Constructed with a modular architecture, the device incorporates a high-strength engineering composite housing and precision-engineered electromagnetic trip mechanism. This dual-function system provides both overload and short-circuit protection. The silver-alloy composite contact system, combined with multi-stage arc quenching technology, effectively reduces arc energy dissipation while extending electrical endurance. The three-position operating mechanism (OFF/ON/RESET) ensures clear status identification and secure mechanical interlocking.
Technical highlights include rear terminal access design for space-efficient panel integration. The bidirectional conductor terminals accommodate copper cables from 35mm² to 240mm² cross-section. Verified through multi-scenario testing, the tripping characteristic curves adapt to various load types including motor circuits and distribution lines. Internal compartmentalization design physically isolates main circuits from auxiliary components, enhancing operational reliability.
This device operates within 380V-690V AC systems at 50/60Hz frequency. With IP40 protection rating, it maintains stable performance in standard industrial environments. The maintenance-friendly design incorporates visual status indicators for quick condition monitoring. Optional accessories including auxiliary alarm contacts and shunt trip modules allow functional customization to meet diverse application requirements.
