The CDM6LI-400M/3300 315A Molded Case Leakage Protection Circuit Breaker is a comprehensive solution for medium-voltage distribution systems, designed for AC 50Hz networks with operational voltage up to 400V. Featuring a modular structure, this device delivers 315A rated current capacity and enhanced operational stability through optimized coordination between arc-extinguishing systems and electromagnetic mechanisms.
Equipped with intelligent leakage monitoring, the product detects residual current in real-time and initiates circuit interruption within 0.1 seconds when thresholds are exceeded. Its three-stage time-delay protection (1/3/5 delay 2) combines long-time overload protection, short-time delay protection and instantaneous tripping functions, ensuring selective coordination under complex operational conditions. The dual-interlock mechanical system effectively prevents operational errors.
Constructed with flame-retardant reinforced nylon, the enclosure achieves IP40 protection rating and operates reliably in temperatures from -25℃ to +70℃. The compact design reduces width by 15% compared to standard models, enabling space-efficient multi-circuit configurations. A transparent inspection window allows visual confirmation of contact status, while versatile mounting options support both 35mm DIN rail and fixed installations.
This device is widely implemented in industrial switchgear, commercial building distribution systems, and public infrastructure networks, providing reliable protection for motors, transformers, and power lines. Optimized conductive path design reduces temperature rise by 8-12K under full load compared to similar products, effectively extending service life. Professional maintenance inspection is recommended every 2-3 years based on operational environment.
Technical Highlights:
- Adaptive trip calibration adjusts to ambient temperature variations
- Reinforced contact system withstands 10,000+ mechanical operations
- Integrated test button simplifies functional verification
- Phase-isolated arc chambers prevent inter-phase interference
- Unified accessory interface supports remote signaling modules
- Corrosion-resistant metal components pass 96hr salt spray test
