CDM1L-225M/4300C Molded Case Leakage Circuit Breaker Product Introduction (English Version)
The CDM1L-225M/4300C series molded case leakage circuit breaker integrates circuit protection and residual current monitoring functions, designed for industrial power distribution systems, commercial buildings, and infrastructure applications. Featuring modular architecture, this device ensures precise current protection while enhancing power supply safety and system reliability.
With rated current of 180A and 4-pole (3P+N) configuration, the product is compatible with 380V distribution networks. Its adjustable earth leakage protection offers three-stage tripping thresholds (30mA/100mA/500mA), allowing flexible configuration for both personal safety protection and equipment leakage monitoring. Integrated overload/short-circuit protection combines with electromagnetic trip mechanism to achieve circuit interruption within 0.1 seconds during fault conditions.
Structural design incorporates high-strength engineering plastic housing and copper alloy contact system, ensuring stable operation within -25℃ to +70℃ temperature range. Silver-based alloy moving contacts minimize resistance, maintaining temperature rise within operational limits. Transparent protective cover enables visual status inspection, while rotary operating handle provides clear ON/OFF indication, supporting both wall-mounted and DIN rail installations.
Ideal for main circuit protection in power distribution systems, motor control centers, and data center power supplies, the breaker demonstrates enhanced protection capability in high-risk environments such as humid areas and temporary power sites. Optimized arc extinguishing chamber and magnetic flux conversion technology deliver 50kA short-circuit breaking capacity, effectively containing fault arc propagation.
Technical parameters include mechanical endurance exceeding 10,000 operations, IP40 protection grade enclosure, and 6kV impulse withstand voltage. The product supports remote alarm contact extension for system integration, with compact dimensional design saving 20% installation space compared to conventional models. Maintenance-friendly structure allows contact status inspection without full disassembly, reducing downtime during routine servicing.
