The CDM6LI-250M/4300A 250A Molded Case Leakage Protection Circuit Breaker is a high-performance electrical protection device designed for low-voltage distribution systems. Integrating earth leakage protection, overload protection and short-circuit protection functions through modular design, this product significantly enhances the safety level of electrical systems. The housing, constructed with high-strength engineering plastics, demonstrates excellent insulation performance and mechanical durability, suitable for various industrial, commercial and residential electrical environments.
With a rated operational current of 250A and ultimate breaking capacity of 4300A, the device reliably interrupts fault currents. Its innovative 1/3/5 three-stage time-delay protection mechanism allows flexible adjustment of tripping time to ensure protection sensitivity while preventing nuisance tripping. The double-break contact structure combined with an efficient arc extinguishing system extends electrical endurance, verified by laboratory tests to withstand over 10,000 normal switching cycles.
Functional enhancements include a visible switching status indicator window and mechanical free-trip mechanism, facilitating operational monitoring and emergency manual intervention. The leakage protection module employs intelligent detection technology to continuously monitor circuit leakage current, initiating automatic circuit interruption within 0.1 seconds upon reaching preset thresholds. Dual mounting options (DIN-rail or bolt fixation) ensure compatibility with various distribution cabinet specifications.
Manufactured under strict quality control processes, key components utilize silver-plated copper alloy contacts to maintain stable conductivity during extended service. The compact design achieves 15% volume reduction compared to similar products while maintaining full functionality. With IP40 protection rating effectively preventing dust ingress, this device is suitable for three-phase four-wire systems up to 400V AC 50Hz, providing reliable protection for motor circuits, power distribution lines and critical electrical equipment.
