CDM3L-250S/4300A 225A 1/3/5 Delay1 Molded Case Leakage Circuit Breaker is an intelligent protection device specifically designed for low-voltage distribution systems. Suitable for 50Hz AC power networks with rated operational voltage up to 400V, this product integrates overload protection, short-circuit protection, and earth leakage protection functions to effectively enhance the safety and reliability of power supply systems.
Featuring modular construction, the main body is manufactured with high-strength insulating materials demonstrating excellent heat resistance and impact tolerance. The 225A rated current design meets core protection requirements for medium-small scale distribution cabinets, while the 4300A high breaking capacity ensures reliable fault current interruption under extreme short-circuit conditions. The 1/3/5 Delay1 timing configuration allows users to customize protection parameters for implementing graded time-delay protection strategies.
The core components combine electromagnetic trip mechanism and electronic leakage detection module, enabling precise identification of ground fault currents ranging from 30mA to 30A. The innovatively designed visual status indicator window provides instant operation/fault diagnosis through color-coded displays. Supporting three-level installation options, the device can operate independently or integrate with busbar systems, adapting to various cabinet configurations.
Typical applications include: main circuit protection for commercial building distribution systems, power allocation in industrial production lines, and emergency power supply systems for public facilities requiring leakage protection. The product is designed for standard environmental conditions with recommended operating temperatures between -5℃ to +40℃ and relative humidity not exceeding 90% in indoor environments.
