CDM6LI-630L/4300A Residual Current Circuit Breaker Product Introduction (English Version)
The CDM6LI-630L/4300A molded case residual current circuit breaker is a multifunctional protection device developed for industrial and civil power distribution systems. Designed for AC 50Hz networks with rated operational voltage up to 400V, this product integrates earth leakage protection, overload protection and short-circuit protection in a modular structure, delivering comprehensive safety solutions for low-voltage power systems.
Featuring a high breaking capacity of 4300A, the device ensures reliable interruption of fault currents. Its advanced electronic leakage detection module can identify ground fault currents ranging from 30mA to 30A, triggering circuit disconnection within 0.1 seconds. The 500A rated current version offers three-stage protection characteristics (3/5/10 delay 3), allowing customizable time-delay settings to accommodate motor starting requirements and ensure sensitive protection for lighting systems.
Technologically, the breaker employs high-temperature resistant engineering plastic housing with IP40 protection rating, suitable for operation in wide temperature ranges from -25℃ to +70℃. Its compact design reduces physical dimensions by approximately 18% compared to similar products, enabling optimized panel space utilization. The transparent inspection window with tri-color LED indicators provides real-time status monitoring and fault type identification. The energy-storing quick-make mechanism ensures over 20,000 mechanical operations.
Ideal for commercial buildings, industrial plants, and public facilities, this device demonstrates particular effectiveness in humid environments and high-occupancy areas requiring enhanced electrical safety. By promptly responding to circuit abnormalities, it significantly reduces electrical fire risks while protecting personnel and equipment. Supporting both horizontal and vertical installation options, the modular design allows individual component replacement during maintenance, effectively reducing operational costs.
The product incorporates ergonomic operation interfaces with clear function labeling, facilitating quick parameter adjustment. Special arc-extinguishing chamber design enhances electrical endurance, while the reinforced terminal structure ensures stable connection even under vibration conditions. Optional communication modules can be integrated for remote monitoring applications.
