CDM6LI-400M/4300A 350A Molded Case Leakage Circuit Breaker
The CDM6LI-400M/4300A 350A molded case leakage circuit breaker is an integrated protection device developed for low-voltage distribution systems. Featuring a modular design architecture, it combines earth leakage detection and circuit protection functions into a compact solution. With a rated operational current of 350A and three-pole (3P) configuration, this device incorporates an optimized electromagnetic trip mechanism to deliver hierarchical protection for power distribution networks.
Equipped with a high-sensitivity electronic leakage detection module, the breaker continuously monitors residual current in circuits. Upon detecting leakage current exceeding preset thresholds, the tripping mechanism will disconnect the circuit within 0.1 seconds to mitigate electrical fire hazards. The innovative adjustable time-delay protection (1/3/5 settings) enables selective coordination in multi-level power distribution systems, effectively preventing unnecessary power interruptions.
The main housing utilizes high-strength engineering plastics through integrated molding technology, providing superior insulation and impact resistance. Precision-machined conductive components combined with silver-alloy contacts ensure stable performance under working voltages up to 400V. The optimized buffer mechanism extends mechanical durability to over 10,000 operational cycles. With rail-mounting compatibility and dual-color status indicators, the device simplifies installation and maintenance procedures.
Ideal for industrial plants, commercial complexes, and public buildings, this circuit breaker delivers comprehensive protection against overload, short circuit, and earth leakage for motors, distribution cabinets, and cable systems. Enhanced arc-extinguishing chamber design and improved thermal dissipation significantly reduce arc effects during fault interruption, maintaining power supply continuity and system reliability.
